+\func{int}{wxKill}{\param{long}{ pid}, \param{int}{ sig = wxSIGTERM}, \param{wxKillError }{*rc = NULL}, \param{int }{flags = 0}}
+
+Equivalent to the Unix kill function: send the given signal {\it sig} to the
+process with PID {\it pid}. The valid signal values are
+
+\begin{verbatim}
+enum wxSignal
+{
+ wxSIGNONE = 0, // verify if the process exists under Unix
+ wxSIGHUP,
+ wxSIGINT,
+ wxSIGQUIT,
+ wxSIGILL,
+ wxSIGTRAP,
+ wxSIGABRT,
+ wxSIGEMT,
+ wxSIGFPE,
+ wxSIGKILL, // forcefully kill, dangerous!
+ wxSIGBUS,
+ wxSIGSEGV,
+ wxSIGSYS,
+ wxSIGPIPE,
+ wxSIGALRM,
+ wxSIGTERM // terminate the process gently
+};
+\end{verbatim}
+
+{\tt wxSIGNONE}, {\tt wxSIGKILL} and {\tt wxSIGTERM} have the same meaning
+under both Unix and Windows but all the other signals are equivalent to
+{\tt wxSIGTERM} under Windows.
+
+Returns 0 on success, -1 on failure. If {\it rc} parameter is not NULL, it will
+be filled with an element of {\tt wxKillError} enum:
+
+\begin{verbatim}
+enum wxKillError
+{
+ wxKILL_OK, // no error
+ wxKILL_BAD_SIGNAL, // no such signal
+ wxKILL_ACCESS_DENIED, // permission denied
+ wxKILL_NO_PROCESS, // no such process
+ wxKILL_ERROR // another, unspecified error
+};
+\end{verbatim}
+
+The {\it flags} parameter can be wxKILL\_NOCHILDREN (the default),
+or wxKILL\_CHILDREN, in which case the child processes of this
+process will be killed too. Note that under Unix, for wxKILL\_CHILDREN
+to work you should have created the process by passing wxEXEC\_MAKE\_GROUP\_LEADER
+to wxExecute.

+\section{Thread functions}\label{threadfunctions}
+
+The functions and macros here mainly exist to make it writing the code which
+may be compiled in multi thread build ({\tt wxUSE\_THREADS} $= 1$) as well as
+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.
+

+
+
+
+\membersection{wxCRIT\_SECT\_DECLARE}\label{wxcritsectdeclare}
+
+\func{}{wxCRIT\_SECT\_DECLARE}{\param{}{cs}}
+
+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}
+object named {\it name} and associated with the critical section {\it cs} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$.
+
+
+
+\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{wxENTER\_CRIT\_SECT}\label{wxentercritsect}
+
+\func{}{wxENTER\_CRIT\_SECT}{\param{wxCriticalSection\& }{cs}}
+
+This macro is equivalent to \helpref{cs.Enter()}{wxcriticalsectionenter} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$.
+
+
+
+\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
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$.
+
+
+
+\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
+thread but the main one.
+
+This function is only defined on platforms which support preemptive
+threads.
+
+

+
+Returns the filename for a full path. The second form returns a pointer to
+temporary storage that should not be deallocated.
+
+
+\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}
+
+As of wx 2.5.2, these functions are not thread-safe! (use static variables)
+
+{\it spec} may contain wildcards.
+
+{\it flags} may be wxDIR for restricting the query to directories, wxFILE for files or zero for either.
+
+For example:
+
+\begin{verbatim}
+ wxString f = wxFindFirstFile("/home/project/*.*");
+ while ( !f.empty() )
+ {
+ ...
+ f = wxFindNextFile();
+ }
+\end{verbatim}

+
+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.
+
+\wxheading{Returns}
+
+{\tt true} on success, {\tt false} if an error occured (for example, the
+directory doesn't exist).
+
+\wxheading{Portability}
+
+This function is implemented for Win32,

+
+
+\membersection{::wxPathOnly}\label{wxpathonly}
+
+\func{wxString}{wxPathOnly}{\param{const wxString\& }{path}}

+
+Converts a Unix to a DOS filename by replacing forward
+slashes with backslashes.
+
+
+\membersection{wxCHANGE\_UMASK}\label{wxchangeumask}
+
+\func{}{wxCHANGE\_UMASK}{\param{int }{mask}}
+
+Under Unix this macro changes the current process umask to the given value,
+unless it is equal to $-1$ in which case nothing is done, and restores it to
+the original value on scope exit. It works by declaring a variable which sets
+umask to \arg{mask} in its constructor and restores it in its destructor.

+\func{wxString}{wxGetWorkingDirectory}{\param{char *}{buf=NULL}, \param{int }{sz=1000}}
+
+{\bf NB:} This function is obsolete: use \helpref{wxGetCwd}{wxgetcwd} instead.
+
+Copies the current working directory into the buffer if supplied, or

+\membersection{::wxMatchWild}\label{wxmatchwild}
+
+\func{bool}{wxMatchWild}{\param{const wxString\& }{pattern}, \param{const wxString\& }{text}, \param{bool}{ dot\_special}}
+
+Returns true if the \arg{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}.
+

+\func{int}{wxParseCommonDialogsFilter}{\param{const wxString\& }{wildCard}, \param{wxArrayString\& }{descriptions}, \param{wxArrayString\& }{filters}}
+
+Parses the \arg{wildCard}, returning the number of filters.
+Returns 0 if none or if there's a problem.
+The arrays will contain an equal number of items found before the error.
+On platforms where native dialogs handle only one filter per entry,
+entries in arrays are automatically adjusted.
+\arg{wildCard} is in the form:
+\begin{verbatim}

+
+{\bf NB:} This function is obsolete, please use
+\helpref{wxFileName::SplitPath}{wxfilenamesplitpath} instead.
+
+This function splits a full file name into components: the path (including possible disk/drive
+specification under Windows), the base name and the extension. Any of the output parameters
+({\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
+Windows, however it will not consider backslashes as path separators under Unix (where backslash
+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
+three of them may be empty if the corresponding component is. The old contents of the
+strings pointed to by these parameters will be overwritten in any case (if the pointers
+are not NULL).
