Writes data to a stream, without locking the thread.
size_t _fwrite_nolock(
const void *buffer,
size_t size,
size_t count,
FILE *stream
);
Parameters
buffer
Pointer to the data to be written.size
Item size in bytes.count
Maximum number of items to be written.stream
Pointer to the FILE structure.
Return Value
Same as fwrite.
Remarks
This function is a non-locking version of fwrite. It is identical to fwrite 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.
