Заметки

These functions are the non-locking versions of fseek and _fseeki64, respectively.These are identical to fseek and _fseeki64 except 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.
