Flushes a stream without locking the thread.

int _fflush_nolock(   
   FILE *stream   


Pointer to the FILE structure.

See fflush.

This function is a non-locking version of fflush. It is identical to fflush except that it is not protected from interference by other threads. It might be faster because it does not incur the overhead of locking out other threads. Use this function only in thread-safe contexts such as single-threaded applications or where the calling scope already handles thread isolation.
