_fflush_nolock
Flushes a stream without locking.
C
int _fflush_nolock(
FILE *stream
);
stream
Pointer to the FILE structure.
See fflush.
This function is a non-locking version of fflush. It's identical to fflush except that it isn't protected from interference by other threads. It might be faster because it doesn't 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.
By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.
