PtPreventExit()

Prevent a Photon application from exiting

Synopsis:

void PtPreventExit( void );

Library:

ph

Description:

PtPreventExit() lets Photon know that it isn't 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.
