Reads data from a stream, without locking other threads.
Syntax
size_t _fread_nolock(
void *buffer,
size_t size,
size_t count,
FILE *stream
);
Parameters
buffer
Storage location for data.
size
Item size in bytes.
count
Maximum number of items to be read.
stream
Pointer to the FILE structure.
Return Value

Remarks
This function is a non-locking version of fread. It is identical to fread 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.
