 | ||
| 
 | ||
|     In the overloaded versions of this function, if @a flags parameter contains
 | ||
|     @c wxEXEC_ASYNC flag (the default), flow of control immediately returns. If
 | ||
|     it contains @c 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 -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 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 @c wxEXEC_NODISABLE flag to prevent this
 | ||
|     automatic disabling from happening.
 | ||
| 
 | ||
|     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 when using DDE under Windows for command execution). In particular,
 | ||
|     in this case only, the calling code will not get the notification about
 | ||
|     process termination.
 | ||
| 
 | ||
|     If @a callback isn't @NULL and if execution is asynchronous,
 | ||
|     wxProcess::OnTerminate() 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
 | ||
|     wxProcess::Redirect().
 | ||
| 
 | ||
|     Under Windows, when launching a console process its console is shown by
 | ||
|     default but hidden if its IO is redirected. Both of these default
 | ||
|     behaviours may be overridden: if ::wxEXEC_HIDE_CONSOLE is specified, the
 | ||
|     console will never be shown. If ::wxEXEC_SHOW_CONSOLE is used, the console
 | ||
|     will be shown even if the child process IO is redirected. Neither of these
 | ||
|     flags affect non-console Windows applications or does anything under the
 | ||
|     other systems.
 | ||
| 
 | ||
|     Under Unix the flag @c 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 wxKill() passing wxKILL_CHILDREN will kill this process as
 | ||
|     well as all of its children (except those which have started their own
 | ||
|     session). Under MSW, this flag can be used with console processes only and
 | ||
|     corresponds to the native @c CREATE_NEW_PROCESS_GROUP flag.
 | ||
| 
 | ||
|     The @c wxEXEC_NOEVENTS flag prevents processing of any events from taking
 | ||
|     place while the child process is running. It should be only used for very
 | ||
|     short-lived processes as otherwise the application windows risk becoming
 | ||
|     unresponsive from the users point of view. As this flag only makes sense
 | ||
|     with @c wxEXEC_SYNC, @c wxEXEC_BLOCK equal to the sum of both of these
 | ||
|     flags is provided as a convenience.
 | ||
| 
 | ||
|     @note Currently wxExecute() can only be used from the main thread, calling
 | ||
|           this function from another thread will result in an assert failure in
 | ||
|           debug build and won't work.
