_fflush_nolock
Flushes a stream without locking the thread.
Syntax
int _fflush_nolock(
FILE *stream
);
Parameters
stream
Pointer to the FILE structure.
Return Value
See fflush.
Remarks
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.
By default, this function's global state is scoped to the application. To change this, see Global state in the CRT.
