+\section{Version macros}\label{versionfunctions}
+
+The following constants are defined in wxWindows:
-\section{File functions}\label{filefunctions}
-
-\wxheading{Include files}
-
-<wx/utils.h>
+\begin{itemize}\itemsep=0pt
+\item {\tt wxMAJOR\_VERSION} is the major version of wxWindows
+\item {\tt wxMINOR\_VERSION} is the minor version of wxWindows
+\item {\tt wxRELEASE\_NUMBER} is the release number
+\end{itemize}
-\wxheading{See also}
+For example, the values or these constants for wxWindows 2.1.15 are 2, 1 and
+15.
-\helpref{wxPathList}{wxpathlist}
+Additionally, {\tt wxVERSION\_STRING} is a user-readable string containing
+the full wxWindows version and {\tt wxVERSION\_NUMBER} is a combination of the
+three version numbers above: for 2.1.15, it is 2115 and it is 2200 for
+wxWindows 2.2.
-\membersection{::wxDirExists}
+\wxheading{Include files}
-\func{bool}{wxDirExists}{\param{const wxString\& }{dirname}}
+<wx/version.h> or <wx/defs.h>
-Returns TRUE if the directory exists.
+\membersection{wxCHECK\_VERSION}\label{wxcheckversion}
-\membersection{::wxDos2UnixFilename}
+\func{bool}{wxCHECK\_VERSION}{\param{}{major, minor, release}}
-\func{void}{Dos2UnixFilename}{\param{const wxString\& }{s}}
+This is a macro which evaluates to true if the current wxWindows version is at
+least major.minor.release.
-Converts a DOS to a Unix filename by replacing backslashes with forward
-slashes.
+For example, to test if the program is compiled with wxWindows 2.2 or higher,
+the following can be done:
-\membersection{::wxFileExists}
+\begin{verbatim}
+ wxString s;
+#if wxCHECK_VERSION(2, 2, 0)
+ if ( s.StartsWith("foo") )
+#else // replacement code for old version
+ if ( strncmp(s, "foo", 3) == 0 )
+#endif
+ {
+ ...
+ }
+\end{verbatim}
-\func{bool}{wxFileExists}{\param{const wxString\& }{filename}}
+\section{Application initialization and termination}\label{appinifunctions}
-Returns TRUE if the file exists. It also returns TRUE if the file is
-a directory.
+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.
-\membersection{::wxFileNameFromPath}
+\membersection{::wxEntry}\label{wxentry}
-\func{wxString}{wxFileNameFromPath}{\param{const wxString\& }{path}}
+This initializes wxWindows in a platform-dependent way. Use this if you
+are not using the default wxWindows entry code (e.g. main or WinMain). For example,
+you can initialize wxWindows from an Microsoft Foundation Classes application using
+this function.
-\func{char*}{wxFileNameFromPath}{\param{char* }{path}}
+\func{void}{wxEntry}{\param{HANDLE}{ hInstance}, \param{HANDLE}{ hPrevInstance},
+ \param{const wxString\& }{commandLine}, \param{int}{ cmdShow}, \param{bool}{ enterLoop = TRUE}}
-Returns the filename for a full path. The second form returns a pointer to
-temporary storage that should not be deallocated.
+wxWindows initialization under Windows (non-DLL). If {\it enterLoop} is FALSE, the
+function will return immediately after calling wxApp::OnInit. Otherwise, the wxWindows
+message loop will be entered.
-\membersection{::wxFindFirstFile}\label{wxfindfirstfile}
+\func{void}{wxEntry}{\param{HANDLE}{ hInstance}, \param{HANDLE}{ hPrevInstance},
+ \param{WORD}{ wDataSegment}, \param{WORD}{ wHeapSize}, \param{const wxString\& }{ commandLine}}
-\func{wxString}{wxFindFirstFile}{\param{const char*}{spec}, \param{int}{ flags = 0}}
+wxWindows initialization under Windows (for applications constructed as a DLL).
-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 "..".
+\func{int}{wxEntry}{\param{int}{ argc}, \param{const wxString\& *}{argv}}
-{\it spec} may contain wildcards.
+wxWindows initialization under Unix.
-{\it flags} may be wxDIR for restricting the query to directories, wxFILE for files or zero for either.
+\wxheading{Remarks}
-For example:
+To clean up wxWindows, call wxApp::OnExit followed by the static function
+wxApp::CleanUp. For example, if exiting from an MFC application that also uses wxWindows:
\begin{verbatim}
- wxString f = wxFindFirstFile("/home/project/*.*");
- while ( !f.IsEmpty() )
- {
- ...
- f = wxFindNextFile();
- }
-\end{verbatim}
-
-\membersection{::wxFindNextFile}\label{wxfindnextfile}
+int CTheApp::ExitInstance()
+{
+ // OnExit isn't called by CleanUp so must be called explicitly.
+ wxTheApp->OnExit();
+ wxApp::CleanUp();
-\func{wxString}{wxFindNextFile}{\void}
+ return CWinApp::ExitInstance();
+}
+\end{verbatim}
-Returns the next file that matches the path passed to \helpref{wxFindFirstFile}{wxfindfirstfile}.
+\wxheading{Include files}
-See \helpref{wxFindFirstFile}{wxfindfirstfile} for an example.
+<wx/app.h>
-\membersection{::wxGetOSDirectory}\label{wxgetosdirectory}
+\membersection{::wxHandleFatalExceptions}\label{wxhandlefatalexceptions}
-\func{wxString}{wxGetOSDirectory}{\void}
+\func{bool}{wxHandleFatalExceptions}{\param{bool}{ doIt = TRUE}}
-Returns the Windows directory under Windows; on other platforms returns the empty string.
+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.
\membersection{::wxInitAllImageHandlers}\label{wxinitallimagehandlers}
\func{void}{wxInitAllImageHandlers}{\void}
-Adds some common image format handlers, which, depending on wxWindows
-configuration, can be handlers for BMP (loading) (always installed), GIF
-(loading), PCX (loading), PNM (loading and saving as raw
-rgb), PNG (loading and saving), JPEG (loading and saving), file formats.
+Initializes all available image handlers. For a list of available handlers,
+see \helpref{wxImage}{wximage}.
-See also: \helpref{wxImage}{wximage} \helpref{wxImageHandler}{wximagehandler}
+\wxheading{See also}
-\membersection{::wxIsAbsolutePath}
+\helpref{wxImage}{wximage}, \helpref{wxImageHandler}{wximagehandler}
-\func{bool}{wxIsAbsolutePath}{\param{const wxString\& }{filename}}
+\wxheading{Include files}
-Returns TRUE if the argument is an absolute filename, i.e. with a slash
-or drive name at the beginning.
+<wx/image.h>
-\membersection{::wxPathOnly}
+\membersection{::wxInitialize}\label{wxinitialize}
-\func{wxString}{wxPathOnly}{\param{const wxString\& }{path}}
+\func{bool}{wxInitialize}{\void}
-Returns the directory part of the filename.
+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 wxWindows functions.
-\membersection{::wxUnix2DosFilename}
+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.
-\func{void}{wxUnix2DosFilename}{\param{const wxString\& }{s}}
+This function may be called several times but
+\helpref{wxUninitialize}{wxuninitialize} must be called for each successful
+call to this function.
-Converts a Unix to a DOS filename by replacing forward
-slashes with backslashes.
+\wxheading{Include files}
-\membersection{::wxConcatFiles}
+<wx/app.h>
-\func{bool}{wxConcatFiles}{\param{const wxString\& }{file1}, \param{const wxString\& }{file2},
-\param{const wxString\& }{file3}}
+\membersection{::wxSafeYield}\label{wxsafeyield}
-Concatenates {\it file1} and {\it file2} to {\it file3}, returning
-TRUE if successful.
+\func{bool}{wxSafeYield}{\param{wxWindow*}{ win = NULL}}
-\membersection{::wxCopyFile}
+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{bool}{wxCopyFile}{\param{const wxString\& }{file1}, \param{const wxString\& }{file2}}
+Returns the result of the call to \helpref{::wxYield}{wxyield}.
-Copies {\it file1} to {\it file2}, returning TRUE if successful.
+\wxheading{Include files}
-\membersection{::wxGetCwd}\label{wxgetcwd}
+<wx/utils.h>
-\func{wxString}{wxGetCwd}{\void}
+\membersection{::wxUninitialize}\label{wxuninitialize}
-Returns a string containing the current (or working) directory.
+\func{void}{wxUninitialize}{\void}
-\membersection{::wxGetWorkingDirectory}
+This function is for use in console (wxBase) programs only. It must be called
+once for each previous successful call to \helpref{wxInitialize}{wxinitialize}.
-\func{wxString}{wxGetWorkingDirectory}{\param{char*}{buf=NULL}, \param{int }{sz=1000}}
+\wxheading{Include files}
-This function is obsolete: use \helpref{wxGetCwd}{wxgetcwd} instead.
+<wx/app.h>
-Copies the current working directory into the buffer if supplied, or
-copies the working directory into new storage (which you must delete yourself)
-if the buffer is NULL.
+\membersection{::wxYield}\label{wxyield}
-{\it sz} is the size of the buffer if supplied.
+\func{bool}{wxYield}{\void}
-\membersection{::wxGetTempFileName}
+Calls \helpref{wxApp::Yield}{wxappyield}.
-\func{char*}{wxGetTempFileName}{\param{const wxString\& }{prefix}, \param{char* }{buf=NULL}}
+This function is kept only for backwards compatibility, please use
+\helpref{wxApp::Yield}{wxappyield}method instead in any new code.
-\func{bool}{wxGetTempFileName}{\param{const wxString\& }{prefix}, \param{wxString\& }{buf}}
+\wxheading{Include files}
-Makes a temporary filename based on {\it prefix}, opens and closes the file,
-and places the name in {\it buf}. If {\it buf} is NULL, new store
-is allocated for the temporary filename using {\it new}.
+<wx/app.h> or <wx/utils.h>
-Under Windows, the filename will include the drive and name of the
-directory allocated for temporary files (usually the contents of the
-TEMP variable). Under Unix, the {\tt /tmp} directory is used.
+\membersection{::wxWakeUpIdle}\label{wxwakeupidle}
-It is the application's responsibility to create and delete the file.
+\func{void}{wxWakeUpIdle}{\void}
-\membersection{::wxIsWild}\label{wxiswild}
+This functions wakes up the (internal and platform dependent) idle system, i.e. it
+will force the system to send an idle event even if the system currently {\it is}
+ idle and thus would not send any idle event until after some other event would get
+sent. This is also useful for sending events between two threads and is used by
+the corresponding functions \helpref{::wxPostEvent}{wxpostevent} and
+\helpref{wxEvtHandler::AddPendingEvent}{wxevthandleraddpendingevent}.
-\func{bool}{wxIsWild}{\param{const wxString\& }{pattern}}
+\wxheading{Include files}
-Returns TRUE if the pattern contains wildcards. See \helpref{wxMatchWild}{wxmatchwild}.
+<wx/app.h>
-\membersection{::wxMatchWild}\label{wxmatchwild}
+\section{Process control functions}\label{processfunctions}
-\func{bool}{wxMatchWild}{\param{const wxString\& }{pattern}, \param{const wxString\& }{text}, \param{bool}{ dot\_special}}
+The functions in this section are used to launch or terminate the other
+processes.
-Returns TRUE if the {\it pattern}\/ matches the {\it text}\/; if {\it
-dot\_special}\/ is TRUE, filenames beginning with a dot are not matched
-with wildcard characters. See \helpref{wxIsWild}{wxiswild}.
+\membersection{::wxExecute}\label{wxexecute}
-\membersection{::wxMkdir}
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{int }{sync = wxEXEC\_ASYNC}, \param{wxProcess *}{callback = NULL}}
-\func{bool}{wxMkdir}{\param{const wxString\& }{dir}, \param{int }{perm = 0777}}
+\func{long}{wxExecute}{\param{char **}{argv}, \param{int }{flags = wxEXEC\_ASYNC}, \param{wxProcess *}{callback = NULL}}
-Makes the directory {\it dir}, returning TRUE if successful.
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{wxArrayString\& }{output}}
-{\it perm} is the access mask for the directory for the systems on which it is
-supported (Unix) and doesn't have effect for the other ones.
+\perlnote{In wxPerl this function only takes the {\tt command} argument,
+and returns a 2-element list {\tt ( status, output )}, where {\tt output} is
+an array reference.}
-\membersection{::wxRemoveFile}
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{wxArrayString\& }{output}, \param{wxArrayString\& }{errors}}
-\func{bool}{wxRemoveFile}{\param{const wxString\& }{file}}
+\perlnote{In wxPerl this function only takes the {\tt command} argument,
+and returns a 3-element list {\tt ( status, output, errors )}, where
+{\tt output} and {\tt errors} are array references.}
-Removes {\it file}, returning TRUE if successful.
+Executes another program in Unix or Windows.
-\membersection{::wxRenameFile}
+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 second form takes an array of values: a command, any number of
+arguments, terminated by NULL.
-Renames {\it file1} to {\it file2}, returning TRUE if successful.
+The semantics of the third and fourth versions is different from the first two
+and is described in more details below.
-\membersection{::wxRmdir}
+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.
-\func{bool}{wxRmdir}{\param{const wxString\& }{dir}, \param{int}{ flags=0}}
+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}. The caller
+should ensure that this can cause no recursion, in the simplest case by
+calling \helpref{wxEnableTopLevelWindows(FALSE)}{wxenabletoplevelwindows}.
-Removes the directory {\it dir}, returning TRUE if successful. Does not work under VMS.
+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.
+
+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

+\func{classname *}{wxDynamicCast}{ptr, classname}
-Yields control to pending messages in the windowing system. This can be useful, for example, when a
-time-consuming process writes to a text window. Without an occasional
-yield, the text window will not be updated properly, and (since Windows
-multitasking is cooperative) other processes will not respond.
+This macro returns the pointer {\it ptr} cast to the type {\it classname *} if
+the pointer is of this type (the check is done during the run-time) or
+{\tt NULL} otherwise. Usage of this macro is preferred over obsoleted
+wxObject::IsKindOf() function.
-Caution should be exercised, however, since yielding may allow the
-user to perform actions which are not compatible with the current task.
-Disabling menu items or whole menus during processing can avoid unwanted
-reentrance of code: see \helpref{::wxSafeYield}{wxsafeyield} for a better
-function.
+The {\it ptr} argument may be {\tt NULL}, in which case {\tt NULL} will be
+returned.

+(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

+\membersection{wxGetEnv}\label{wxgetenv}
+
+\func{bool}{wxGetEnv}{\param{const wxString\&}{ var}, \param{wxString *}{value}}
+
+Returns the current value of the environment variable {\it var} in {\it value}.

+and are not interested in its value.
+
+Returns {\tt TRUE} if the variable exists, {\tt FALSE} otherwise.
+
+\membersection{wxSetEnv}\label{wxsetenv}
+
+\func{bool}{wxSetEnv}{\param{const wxString\&}{ var}, \param{const wxChar *}{value}}
+
+Sets the value of the environment variable {\it var} (adding it if necessary)
+to {\it value}.
+
+Returns {\tt TRUE} on success.
+
+\membersection{wxUnsetEnv}\label{wxunsetenv}
+
+\func{bool}{wxUnsetEnv}{\param{const wxString\&}{ var}}
+
