Executes another program in Unix or Windows.
The first form takes a command string, such as {\tt "emacs file.txt"}.
The semantics of the third and fourth versions is different from the first two
and is described in more details below.
-If {\it sync} is FALSE (the default), flow of control immediately returns.
-If TRUE, the current application waits until the other program has terminated.
+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.
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
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),
+If callback isn't NULL and if execution is asynchronous,
\helpref{wxProcess::OnTerminate}{wxprocessonterminate} will be called when
-the process finishes.
+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} with the argument of -pid where pid
+is the process ID of the new process will kill this process as well as all of
+its children (except those which have started their own session).
Finally, you may use the third overloaded version of this function to execute
a process (always synchronously) and capture its output in the array

-This function posts the event to the specified {\it dest} object. The
-difference between sending an event and posting it is that in the first case
-the event is processed before the function returns (in wxWindows, event sending
-is done with \helpref{ProcessEvent}{wxevthandlerprocessevent} function), but in
-the second, the function returns immediately and the event will be processed
-sometime later - usually during the next even loop iteration.
-
-Note that a copy of the {\it event} is made by the function, so the original
-copy can be deleted as soon as function returns. This function can also be used
-to send events between different threads safely. As this function makes a
-copy of the event, the event needs to have a fully implemented Clone() method,
-which may not be the case for all event in wxWindows.
-
-See also \helpref{AddPendingEvent}{wxevthandleraddpendingevent} (which this function
-uses internally).
+In a GUI application, this function posts {\it event} to the specified {\it dest}
