-
-\membersection{::wxMutexGuiEnter}\label{wxmutexguienter}
-
-\func{void}{wxMutexGuiEnter}{\void}
-
-This function must be called when any thread other than the main GUI thread
-wants to get access to the GUI library. This function will block the execution
-of the calling thread until the main thread (or any other thread holding the
-main GUI lock) leaves the GUI library and no other thread will enter the GUI
-library until the calling thread calls \helpref{::wxMutexGuiLeave()}{wxmutexguileave}.
-
-Typically, these functions are used like this:
-
-\begin{verbatim}
-void MyThread::Foo(void)
-{
- // before doing any GUI calls we must ensure that this thread is the only
- // one doing it!
- wxMutexGuiEnter();
+\membersection{wxCHECK\_VERSION\_FULL}\label{wxcheckversionfull}
- // Call GUI here:
- my_window->DrawSomething();
+\func{bool}{wxCHECK\_VERSION\_FULL}{\param{}{major, minor, release, subrel}}
- wxMutexGuiLeave();
-}
-\end{verbatim}
+Same as \helpref{wxCHECK\_VERSION}{wxcheckversion} but also checks that
+\texttt{wxSUBRELEASE\_NUMBER} is at least \arg{subrel}.
-Note that under GTK, no creation of top-level windows is allowed in any
-thread but the main one.
-This function is only defined on platforms which support preemptive
-threads.
+\membersection{wxCHECK\_W32API\_VERSION}\label{wxcheckw32apiversion}
-\membersection{::wxMutexGuiLeave}\label{wxmutexguileave}
+\func{bool}{wxCHECK\_GCC\_VERSION}{\param{}{major, minor, release}}
-\func{void}{wxMutexGuiLeave}{\void}
+Returns $1$ if the version of w32api headers used is major.minor.release or
+greater. Otherwise, and also if we are not compiling with mingw32/cygwin under
+Win32 at all, returns $0$.
-See \helpref{::wxMutexGuiEnter()}{wxmutexguienter}.
-This function is only defined on platforms which support preemptive
-threads.
-\section{File functions}\label{filefunctions}
+\section{Application initialization and termination}\label{appinifunctions}
-\wxheading{Include files}
+The functions in this section are used on application startup/shutdown and also
+to control the behaviour of the main event loop of the GUI programs.
-<wx/utils.h>
-\wxheading{See also}
+\membersection{::wxEntry}\label{wxentry}
-\helpref{wxPathList}{wxpathlist}, \helpref{wxDir}{wxdir}, \helpref{wxFile}{wxfile}
+This initializes wxWidgets in a platform-dependent way. Use this if you
+are not using the default wxWidgets entry code (e.g. main or WinMain). For example,
+you can initialize wxWidgets from an Microsoft Foundation Classes application using
+this function.
-\membersection{::wxDirExists}
+\func{void}{wxEntry}{\param{HANDLE}{ hInstance}, \param{HANDLE}{ hPrevInstance},
+ \param{const wxString\& }{commandLine}, \param{int}{ cmdShow}, \param{bool}{ enterLoop = true}}
-\func{bool}{wxDirExists}{\param{const wxString\& }{dirname}}
+wxWidgets initialization under Windows (non-DLL). If {\it enterLoop} is false, the
+function will return immediately after calling wxApp::OnInit. Otherwise, the wxWidgets
+message loop will be entered.
-Returns TRUE if the directory exists.
+\func{void}{wxEntry}{\param{HANDLE}{ hInstance}, \param{HANDLE}{ hPrevInstance},
+ \param{WORD}{ wDataSegment}, \param{WORD}{ wHeapSize}, \param{const wxString\& }{ commandLine}}
-\membersection{::wxDos2UnixFilename}
+wxWidgets initialization under Windows (for applications constructed as a DLL).
-\func{void}{wxDos2UnixFilename}{\param{wxChar *}{s}}
+\func{int}{wxEntry}{\param{int}{ argc}, \param{const wxString\& *}{argv}}
-Converts a DOS to a Unix filename by replacing backslashes with forward
-slashes.
+wxWidgets initialization under Unix.
-\membersection{::wxFileExists}
+\wxheading{Remarks}
-\func{bool}{wxFileExists}{\param{const wxString\& }{filename}}
+To clean up wxWidgets, call wxApp::OnExit followed by the static function
+wxApp::CleanUp. For example, if exiting from an MFC application that also uses wxWidgets:
-Returns TRUE if the file exists. It also returns TRUE if the file is
-a directory.
+\begin{verbatim}
+int CTheApp::ExitInstance()
+{
+ // OnExit isn't called by CleanUp so must be called explicitly.
+ wxTheApp->OnExit();
+ wxApp::CleanUp();
-\membersection{::wxFileModificationTime}\label{wxfilemodificationtime}
+ return CWinApp::ExitInstance();
+}
+\end{verbatim}
-\func{time\_t}{wxFileModificationTime}{\param{const wxString\& }{filename}}
+\wxheading{Include files}
-Returns time of last modification of given file.
+<wx/app.h>
-\membersection{::wxFileNameFromPath}
-\func{wxString}{wxFileNameFromPath}{\param{const wxString\& }{path}}
-\func{char*}{wxFileNameFromPath}{\param{char* }{path}}
+\membersection{::wxGetApp}\label{wxgetapp}
-Returns the filename for a full path. The second form returns a pointer to
-temporary storage that should not be deallocated.
+\func{wxAppDerivedClass\&}{wxGetApp}{\void}
-\membersection{::wxFindFirstFile}\label{wxfindfirstfile}
+This function doesn't exist in wxWidgets but it is created by using
+the \helpref{IMPLEMENT\_APP}{implementapp} macro. Thus, before using it
+anywhere but in the same module where this macro is used, you must make it
+available using \helpref{DECLARE\_APP}{declareapp}.
-\func{wxString}{wxFindFirstFile}{\param{const char*}{spec}, \param{int}{ flags = 0}}
+The advantage of using this function compared to directly using the global
+wxTheApp pointer is that the latter is of type {\tt wxApp *} and so wouldn't
+allow you to access the functions specific to your application class but not
+present in wxApp while wxGetApp() returns the object of the right type.
-This function does directory searching; returns the first file
-that matches the path {\it spec}, or the empty string. Use \helpref{wxFindNextFile}{wxfindnextfile} to
-get the next matching file. Neither will report the current directory "." or the
-parent directory "..".
-{\it spec} may contain wildcards.
+\membersection{::wxHandleFatalExceptions}\label{wxhandlefatalexceptions}
-{\it flags} may be wxDIR for restricting the query to directories, wxFILE for files or zero for either.
+\func{bool}{wxHandleFatalExceptions}{\param{bool}{ doIt = true}}
-For example:
+If {\it doIt} is true, the fatal exceptions (also known as general protection
+faults under Windows or segmentation violations in the Unix world) will be
+caught and passed to \helpref{wxApp::OnFatalException}{wxapponfatalexception}.
+By default, i.e. before this function is called, they will be handled in the
+normal way which usually just means that the application will be terminated.
+Calling wxHandleFatalExceptions() with {\it doIt} equal to false will restore
+this default behaviour.
-\begin{verbatim}
- wxString f = wxFindFirstFile("/home/project/*.*");
- while ( !f.IsEmpty() )
- {
- ...
- f = wxFindNextFile();
- }
-\end{verbatim}
-\membersection{::wxFindNextFile}\label{wxfindnextfile}
+\membersection{::wxInitAllImageHandlers}\label{wxinitallimagehandlers}
-\func{wxString}{wxFindNextFile}{\void}
+\func{void}{wxInitAllImageHandlers}{\void}
-Returns the next file that matches the path passed to \helpref{wxFindFirstFile}{wxfindfirstfile}.
+Initializes all available image handlers. For a list of available handlers,
+see \helpref{wxImage}{wximage}.
-See \helpref{wxFindFirstFile}{wxfindfirstfile} for an example.
+\wxheading{See also}
-\membersection{::wxGetDiskSpace}\label{wxgetdiskspace}
+\helpref{wxImage}{wximage}, \helpref{wxImageHandler}{wximagehandler}
-\func{bool}{wxGetDiskSpace}{\param{const wxString\& }{path}, \param{wxLongLong }{*total = NULL}, \param{wxLongLong }{*free = NULL}}
+\wxheading{Include files}
-This function returns the total number of bytes and number of free bytes on
-the disk containing the directory {\it path} (it should exist). Both
-{\it total} and {\it free} parameters may be {\tt NULL} if the corresponding
-information is not needed.
+<wx/image.h>
-\wxheading{Returns}
-{\tt TRUE} on success, {\tt FALSE} if an error occured (for example, the
-directory doesn't exist).
+\membersection{::wxInitialize}\label{wxinitialize}
-\wxheading{Portability}
+\func{bool}{wxInitialize}{\void}
-This function is implemented for Win16 (only for drives less than 2Gb), Win32,
-Mac OS and generic Unix provided the system has {\tt statfs()} function.
+This function is used in wxBase only and only if you don't create
+\helpref{wxApp}{wxapp} object at all. In this case you must call it from your
+{\tt main()} function before calling any other wxWidgets functions.
-This function first appeared in wxWindows 2.3.2.
+If the function returns {\tt false} the initialization could not be performed,
+in this case the library cannot be used and
+\helpref{wxUninitialize}{wxuninitialize} shouldn't be called neither.
-\membersection{::wxGetOSDirectory}\label{wxgetosdirectory}
+This function may be called several times but
+\helpref{wxUninitialize}{wxuninitialize} must be called for each successful
+call to this function.
-\func{wxString}{wxGetOSDirectory}{\void}
+\wxheading{Include files}
-Returns the Windows directory under Windows; on other platforms returns the empty string.
+<wx/app.h>
-\membersection{::wxIsAbsolutePath}
-\func{bool}{wxIsAbsolutePath}{\param{const wxString\& }{filename}}
+\membersection{::wxSafeYield}\label{wxsafeyield}
-Returns TRUE if the argument is an absolute filename, i.e. with a slash
-or drive name at the beginning.
+\func{bool}{wxSafeYield}{\param{wxWindow*}{ win = NULL}, \param{bool}{
+ onlyIfNeeded = false}}
-\membersection{::wxPathOnly}
+This function is similar to wxYield, except that it disables the user input to
+all program windows before calling wxYield and re-enables it again
+afterwards. If {\it win} is not NULL, this window will remain enabled,
+allowing the implementation of some limited user interaction.
-\func{wxString}{wxPathOnly}{\param{const wxString\& }{path}}
+Returns the result of the call to \helpref{::wxYield}{wxyield}.
-Returns the directory part of the filename.
+\wxheading{Include files}
-\membersection{::wxUnix2DosFilename}
+<wx/utils.h>
-\func{void}{wxUnix2DosFilename}{\param{const wxString\& }{s}}
-Converts a Unix to a DOS filename by replacing forward
-slashes with backslashes.
+\membersection{::wxUninitialize}\label{wxuninitialize}
-\membersection{::wxConcatFiles}
+\func{void}{wxUninitialize}{\void}
-\func{bool}{wxConcatFiles}{\param{const wxString\& }{file1}, \param{const wxString\& }{file2},
-\param{const wxString\& }{file3}}
+This function is for use in console (wxBase) programs only. It must be called
+once for each previous successful call to \helpref{wxInitialize}{wxinitialize}.
-Concatenates {\it file1} and {\it file2} to {\it file3}, returning
-TRUE if successful.
+\wxheading{Include files}
-\membersection{::wxCopyFile}
+<wx/app.h>
-\func{bool}{wxCopyFile}{\param{const wxString\& }{file1}, \param{const wxString\& }{file2}, \param{bool }{overwrite = TRUE}}
-Copies {\it file1} to {\it file2}, returning TRUE if successful. If
-{\it overwrite} parameter is TRUE (default), the destination file is overwritten
-if it exists, but if {\it overwrite} is FALSE, the functions failes in this
-case.
+\membersection{::wxYield}\label{wxyield}
-\membersection{::wxGetCwd}\label{wxgetcwd}
+\func{bool}{wxYield}{\void}
-\func{wxString}{wxGetCwd}{\void}
+Calls \helpref{wxApp::Yield}{wxappyield}.
-Returns a string containing the current (or working) directory.
+This function is kept only for backwards compatibility. Please use
+the \helpref{wxApp::Yield}{wxappyield} method instead in any new code.
-\membersection{::wxGetWorkingDirectory}
+\wxheading{Include files}
-\func{wxString}{wxGetWorkingDirectory}{\param{char*}{buf=NULL}, \param{int }{sz=1000}}
+<wx/app.h> or <wx/utils.h>

-\func{bool}{wxRemoveFile}{\param{const wxString\& }{file}}
+Executes another program in Unix or Windows.
-Removes {\it file}, returning TRUE if successful.
+The first form takes a command string, such as {\tt "emacs file.txt"}.

-\func{bool}{wxRenameFile}{\param{const wxString\& }{file1}, \param{const wxString\& }{file2}}
+The semantics of the third and fourth versions is different from the first two
+and is described in more details below.
-Renames {\it file1} to {\it file2}, returning TRUE if successful.
+If {\it flags} parameter contains {\tt wxEXEC\_ASYNC} flag (the default), flow
+of control immediately returns. If it contains {\tt wxEXEC\_SYNC}, the current
+application waits until the other program has terminated.
-\membersection{::wxRmdir}
+In the case of synchronous execution, the return value is the exit code of
+the process (which terminates by the moment the function returns) and will be
+$-1$ if the process couldn't be started and typically 0 if the process
+terminated successfully. Also, while waiting for the process to
+terminate, wxExecute will call \helpref{wxYield}{wxyield}. Because of this, by
+default this function disables all application windows to avoid unexpected
+reentrancies which could result from the users interaction with the program
+while the child process is running. If you are sure that it is safe to not
+disable the program windows, you may pass \texttt{wxEXEC\_NODISABLE} flag to
+prevent this automatic disabling from happening.
-\func{bool}{wxRmdir}{\param{const wxString\& }{dir}, \param{int}{ flags=0}}
+For asynchronous execution, however, the return value is the process id and
+zero value indicates that the command could not be executed. As an added
+complication, the return value of $-1$ in this case indicates that we didn't
+launch a new process, but connected to the running one (this can only happen in
+case of using DDE under Windows for command execution). In particular, in this,
+and only this, case the calling code will not get the notification about
+process termination.
-Removes the directory {\it dir}, returning TRUE if successful. Does not work under VMS.
+If callback isn't NULL and if execution is asynchronous,
+\helpref{wxProcess::OnTerminate}{wxprocessonterminate} will be called when
+the process finishes. Specifying this parameter also allows you to redirect the
+standard input and/or output of the process being launched by calling
+\helpref{Redirect}{wxprocessredirect}. If the child process IO is redirected,
+under Windows the process window is not shown by default (this avoids having to
+flush an unnecessary console for the processes which don't create any windows
+anyhow) but a {\tt wxEXEC\_NOHIDE} flag can be used to prevent this from
+happening, i.e. with this flag the child process window will be shown normally.
+
+Under Unix the flag {\tt wxEXEC\_MAKE\_GROUP\_LEADER} may be used to ensure
+that the new process is a group leader (this will create a new session if
+needed). Calling \helpref{wxKill}{wxkill} passing wxKILL\_CHILDREN will
+will kill this process as well as all of its children (except those which have
+started their own session).
-The {\it flags} parameter is reserved for future use.
+Finally, you may use the third overloaded version of this function to execute
+a process (always synchronously, the contents of \arg{flags} is or'd with
+\texttt{wxEXEC\_SYNC}) and capture its output in the array \arg{output}. The
+fourth version adds the possibility to additionally capture the messages from
+standard error output in the \arg{errors} array.
-\membersection{::wxSetWorkingDirectory}
+{\bf NB:} Currently wxExecute() can only be used from the main thread, calling

-This function splits a full file name into components: the path (including possible disk/drive

+\docparam{argv}{The command to execute should be the first element of this

-is a valid character in a filename).
+\docparam{flags}{Combination of bit masks {\tt wxEXEC\_ASYNC},\rtfsp
+{\tt wxEXEC\_SYNC} and {\tt wxEXEC\_NOHIDE}}
-On entry, {\it fullname} should be non-NULL (it may be empty though).
+\docparam{callback}{An optional pointer to \helpref{wxProcess}{wxprocess}}
-On return, {\it path} contains the file path (without the trailing separator), {\it name}
-contains the file name and {\it ext} contains the file extension without leading dot. All

+
+{\tt wxSIGNONE}, {\tt wxSIGKILL} and {\tt wxSIGTERM} have the same meaning
+under both Unix and Windows but all the other signals are equivalent to

+
+Returns 0 on success, -1 on failure. If {\it rc} parameter is not NULL, it will

+
+The {\it flags} parameter can be wxKILL\_NOCHILDREN (the default),

+\section{Thread functions}\label{threadfunctions}

+in single thread configuration ({\tt wxUSE\_THREADS} $= 0$).
+
+For example, a static variable must be protected against simultaneous access by
+multiple threads in the former configuration but in the latter the extra
+overhead of using the critical section is not needed. To solve this problem,
+the \helpref{wxCRITICAL\_SECTION}{wxcriticalsectionmacro} macro may be used
+to create and use the critical section only when needed.

+This macro declares a (static) critical section object named {\it cs} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$.
+
+
+
+\membersection{wxCRIT\_SECT\_DECLARE\_MEMBER}\label{wxcritsectdeclaremember}
+
+\func{}{wxCRIT\_SECT\_DECLARE}{\param{}{cs}}
+
+This macro declares a critical section object named {\it cs} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$. As it doesn't
+include the {\tt static} keyword (unlike
+\helpref{wxCRIT\_SECT\_DECLARE}{wxcritsectdeclare}), it can be used to declare
+a class or struct member which explains its name.
+
+
+
+\membersection{wxCRIT\_SECT\_LOCKER}\label{wxcritsectlocker}
+
+\func{}{wxCRIT\_SECT\_LOCKER}{\param{}{name}, \param{}{cs}}
+
+This macro creates a \helpref{critical section lock}{wxcriticalsectionlocker}

+
+
+
+\membersection{wxCRITICAL\_SECTION}\label{wxcriticalsectionmacro}
+
+\func{}{wxCRITICAL\_SECTION}{\param{}{name}}
+
+This macro combines \helpref{wxCRIT\_SECT\_DECLARE}{wxcritsectdeclare} and
+\helpref{wxCRIT\_SECT\_LOCKER}{wxcritsectlocker}: it creates a static critical
+section object and also the lock object associated with it. Because of this, it
+can be only used inside a function, not at global scope. For example:
+
+\begin{verbatim}
+int IncCount()
+{
+ static int s_counter = 0;
+
+ wxCRITICAL_SECTION(counter);
+
+ return ++s_counter;
+}
+\end{verbatim}
+
+(note that we suppose that the function is called the first time from the main
+thread so that the critical section object is initialized correctly by the time
+other threads start calling it, if this is not the case this approach can
+{\bf not} be used and the critical section must be made a global instead).

+
+
+
+\membersection{::wxIsMainThread}\label{wxismainthread}
+
+\func{bool}{wxIsMainThread}{\void}
+
+Returns {\tt true} if this thread is the main one. Always returns {\tt true} if
+{\tt wxUSE\_THREADS} is $0$.
+
+
+
+\membersection{wxLEAVE\_CRIT\_SECT}\label{wxleavecritsect}
+
+\func{}{wxLEAVE\_CRIT\_SECT}{\param{wxCriticalSection\& }{cs}}
+
+This macro is equivalent to \helpref{cs.Leave()}{wxcriticalsectionleave} if

+
+
+
+\membersection{::wxMutexGuiEnter}\label{wxmutexguienter}
+
+\func{void}{wxMutexGuiEnter}{\void}
+
+This function must be called when any thread other than the main GUI thread
+wants to get access to the GUI library. This function will block the execution
+of the calling thread until the main thread (or any other thread holding the
+main GUI lock) leaves the GUI library and no other thread will enter the GUI
+library until the calling thread calls \helpref{::wxMutexGuiLeave()}{wxmutexguileave}.
+
+Typically, these functions are used like this:
+
+\begin{verbatim}
+void MyThread::Foo(void)
+{
+ // before doing any GUI calls we must ensure that this thread is the only
+ // one doing it!
+
+ wxMutexGuiEnter();
+
+ // Call GUI here:
+ my_window->DrawSomething();
+
+ wxMutexGuiLeave();
+}
+\end{verbatim}
+
+Note that under GTK, no creation of top-level windows is allowed in any

+
+\membersection{::wxFindFirstFile}\label{wxfindfirstfile}
+
+\func{wxString}{wxFindFirstFile}{\param{const char *}{spec}, \param{int}{ flags = 0}}
+
+This function does directory searching; returns the first file
+that matches the path {\it spec}, or the empty string. Use \helpref{wxFindNextFile}{wxfindnextfile} to
+get the next matching file. Neither will report the current directory "." or the
+parent directory "..".
+
+\wxheading{Warning}

+This function splits a full file name into components: the path (including possible disk/drive

+({\it path}, {\it name} or {\it ext}) may be NULL if you are not interested in the value of
+a particular component.
+
+wxSplitPath() will correctly handle filenames with both DOS and Unix path separators under

+is a valid character in a filename).
+
+On entry, {\it fullname} should be non-NULL (it may be empty though).
+
+On return, {\it path} contains the file path (without the trailing separator), {\it name}
+contains the file name and {\it ext} contains the file extension without leading dot. All

+
+This function returns the translation of string {\it str} in the current

+wxT() is a macro which can be used with character and string literals (in other
+words, {\tt 'x'} or {\tt "foo"}) to automatically convert them to Unicode in
+Unicode build configuration. Please see the
+\helpref{Unicode overview}{unicode} for more information.
+
+This macro is simply returns the value passed to it without changes in ASCII
+build. In fact, its definition is:

+#define wxT(x) L ## x
+#else // !Unicode

+\membersection{wxTRANSLATE}\label{wxtranslate}
+
+\func{const wxChar *}{wxTRANSLATE}{\param{const char *}{s}}
+
+This macro doesn't do anything in the program code -- it simply expands to the
+value of its argument (except in Unicode build where it is equivalent to
+\helpref{wxT}{wxt} which makes it unnecessary to use both wxTRANSLATE and wxT
+with the same string which would be really unreadable).
+
+However it does have a purpose and it is to mark the literal strings for the
+extraction into the message catalog created by {\tt xgettext} program. Usually
+this is achieved using \helpref{\_()}{underscore} but that macro not only marks
+the string for extraction but also expands into a
+\helpref{wxGetTranslation}{wxgettranslation} function call which means that it
+cannot be used in some situations, notably for static array
+initialization.
+
+Here is an example which should make it more clear: suppose that you have a
+static array of strings containing the weekday names and which have to be
+translated (note that it is a bad example, really, as
+\helpref{wxDateTime}{wxdatetime} already can be used to get the localized week
+day names already). If you write
+
+\begin{verbatim}
+static const wxChar * const weekdays[] = { _("Mon"), ..., _("Sun") };
+...
+// use weekdays[n] as usual
+\end{verbatim}
+
+the code wouldn't compile because the function calls are forbidden in the array
+initializer. So instead you should do
+
+\begin{verbatim}
+static const wxChar * const weekdays[] = { wxTRANSLATE("Mon"), ..., wxTRANSLATE("Sun") };
+...
+// use wxGetTranslation(weekdays[n])
+\end{verbatim}
+
+here.
+
+Note that although the code {\bf would} compile if you simply omit
+wxTRANSLATE() in the above, it wouldn't work as expected because there would be
+no translations for the weekday names in the program message catalog and
+wxGetTranslation wouldn't find them.

-The first form takes a command string, such as {\tt "emacs file.txt"}.
+Sets the scaling factor for PostScript output. The default is 1.0, 1.0.

-and is described in more details below.
+\membersection{::wxSetPrinterTranslation}\label{wxsetprintertranslation}
-If {\it sync} is FALSE (the default), flow of control immediately returns.
-If TRUE, the current application waits until the other program has terminated.
+\func{void}{wxSetPrinterTranslation}{\param{float }{x}, \param{float }{y}}
-In the case of synchronous execution, the return value is the exit code of
-the process (which terminates by the moment the function returns) and will be

-terminated successfully. Also, while waiting for the process to

+Sets the translation (from the top left corner) for PostScript output. The default is 0.0, 0.0.
-For asynchronous execution, however, the return value is the process id and
-zero value indicates that the command could not be executed. As an added
-complication, the return value of $-1$ in this case indicattes that we didn't
-launch a new process, but connected to the running one (this can only happen in
-case of using DDE under Windows for command execution). In particular, in this,
-and only this, case the calling code will not get the notification about
-process termination.
-If callback isn't NULL and if execution is asynchronous (note that callback
-parameter can not be non-NULL for synchronous execution),
-\helpref{wxProcess::OnTerminate}{wxprocessonterminate} will be called when
-the process finishes.
-Finally, you may use the third overloaded version of this function to execute
-a process (always synchronously) and capture its output in the array
-{\it output}. The fourth version adds the possibility to additionally capture
-the messages from standard error output in the {\it errors} array.

+\section{RTTI functions}\label{rttimacros}
+
+wxWidgets uses its own RTTI ("run-time type identification") system which
+predates the current standard C++ RTTI and so is kept for backwards
+compatibility reasons but also because it allows some things which the
+standard RTTI doesn't directly support (such as creating a class from its
+name).
+
+The standard C++ RTTI can be used in the user code without any problems and in
+general you shouldn't need to use the functions and the macros in this section

\section{Debugging macros and functions}\label{debugmacros}

-builds.
+Useful macros and functions for error checking and defensive programming.
+wxWidgets defines three families of the assert-like macros:
+the wxASSERT and wxFAIL macros only do anything if \_\_WXDEBUG\_\_ is defined
+(in other words, in the debug build) but disappear completely in the release
+build. On the other hand, the wxCHECK macros stay event in release builds but a
+check failure doesn't generate any user-visible effects then. Finally, the
+compile time assertions don't happen during the run-time but result in the
+compilation error messages if the condition they check fail.

+\func{void}{wxOnAssert}{\param{const char *}{fileName}, \param{int}{ lineNumber}, \param{const char *}{cond}, \param{const char *}{msg = NULL}}
+
+This function is called whenever one of debugging macros fails (i.e. condition
+is false in an assertion). It is only defined in the debug mode, in release
+builds the \helpref{wxCHECK}{wxcheck} failures don't result in anything.
+
+To override the default behaviour in the debug builds which is to show the user
+a dialog asking whether he wants to abort the program, continue or continue
+ignoring any subsequent assert failures, you may override
+\helpref{wxApp::OnAssert}{wxapponassert} which is called by this function if
+the global application object exists.
-This function may be redefined to do something non trivial and is called
-whenever one of debugging macros fails (i.e. condition is false in an
-assertion).
-% TODO: this should probably be an overridable in wxApp.
\membersection{wxASSERT}\label{wxassert}
\func{}{wxASSERT}{\param{}{condition}}
-Assert macro. An error message will be generated if the condition is FALSE in
+Assert macro. An error message will be generated if the condition is false in
debug mode, but nothing will be done in the release build.
Please note that the condition in wxASSERT() should have no side effects
because it will not be executed in release mode at all.

+\membersection{wxASSERT\_MIN\_BITSIZE}\label{wxassertminbitsize}
+
+\func{}{wxASSERT\_MIN\_BITSIZE}{\param{}{type}, \param{}{size}}
+
+This macro results in a
+\helpref{compile time assertion failure}{wxcompiletimeassert} if the size
+of the given type {\it type} is less than {\it size} bits.
+
+You may use it like this, for example:
+
+\begin{verbatim}
+ // we rely on the int being able to hold values up to 2^32
+ wxASSERT_MIN_BITSIZE(int, 32);
+
+ // can't work with the platforms using UTF-8 for wchar_t

+
+Using {\tt wxCOMPILE\_TIME\_ASSERT} results in a compilation error if the
+specified {\it condition} is false. The compiler error message should include
+the {\it msg} identifier - please note that it must be a valid C++ identifier
+and not a string unlike in the other cases.
+
+This macro is mostly useful for testing the expressions involving the
+{\tt sizeof} operator as they can't be tested by the preprocessor but it is
+sometimes desirable to test them at the compile time.
+
+Note that this macro internally declares a struct whose name it tries to make
+unique by using the {\tt \_\_LINE\_\_} in it but it may still not work if you
+use it on the same line in two different source files. In this case you may
+either change the line in which either of them appears on or use the
+\helpref{wxCOMPILE\_TIME\_ASSERT2}{wxcompiletimeassert2} macro.
+
+Also note that Microsoft Visual C++ has a bug which results in compiler errors
+if you use this macro with `Program Database For Edit And Continue'
+(\texttt{/ZI}) option, so you shouldn't use it (`Program Database'
+(\texttt{/Zi}) is ok though) for the code making use of this macro.
