_fclose_nolock
Closes a stream without thread-locking.
Syntax
int _fclose_nolock(
FILE *stream
);
Parameters
stream
Pointer to the FILE structure.
Return Value
fclose returns 0 if the stream is successfully closed. Returns EOF to indicate an error.
Remarks
This functions is a non-locking version of fclose. It is identical 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.
