  • Article

Reads data from a stream, without locking other threads.

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.

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.
