fseek #include <cstdio> int fseek( FILE *stream, long offset, int origin ); The function fseek() sets the file position data for the given stream. The origin value should have one of the following values (defined in cstdio): Name Explanation SEEK_SET Seek from the start of the file SEEK_CUR Seek from the current location SEEK_END Seek from the end of the file fseek() returns zero upon success, non-zero on failure.
