Gets the current position of a file pointer, without locking the thread.
long _ftell_nolock( FILE *stream ); __int64 _ftelli64_nolock( FILE *stream );
_ftelli64. For more information, see ftell, _ftelli64.
These functions are non-locking versions of
_ftelli64, respectively. They are identical to
_ftelli64except that they are not protected from interference by other threads. These functions might be faster because they do not incur the overhead of locking out other threads. Use these functions only in thread-safe contexts such as single-threaded applications or where the calling scope already handles thread isolation.
