_fread_nolock

   void *buffer,
   size_t size,
   size_t count,

);

stream

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.
