Allow a Photon application to exit
void PtAllowExit( void );
ph
PtAllowExit() lets
Photon know that it's safe to exit your application.
In a multithreaded application, any thread can call PtExit(), but another
thread might be in the middle of an important operation, such as writing
a file. To prevent this situation from arising, call PtPreventExit() before
starting the operation, and call PtAllowExit() when it's
done.
|
Instead of calling PtPreventExit() and PtAllowExit() directly,
you're better off calling PtEnter() and PtLeave() with Pt_DELAY_EXIT set
in the flags. For a discussion of the difference between these functions
and using Pt_DELAY_EXIT, see “Exiting a multithreaded program” in
the Parallel Operations chapter of the Photon Programmer's
Guide. |
