Defined in header
int fseek( std::FILE* stream, long offset, int origin );
Sets the file position indicator for the file stream
stream is open in binary mode, the new position is exactly
offset bytes measured from the beginning of the file if
origin is SEEK_SET, from the current file position if
origin is SEEK_CUR, and from the end of the file if
origin is SEEK_END. Some binary streams may not support the SEEK_END.
stream is open in text mode, the only supported values for
offset are zero (which works with any
origin) and a value returned by an earlier call to std::ftell on a stream associated with the same file (which only works with
origin of SEEK_SET.
In addition to changing the file position indicator,
fseek undoes the effects of std::ungetc and clears the end-of-file status, if applicable.
If a read or write error occurs, the error indicator for the stream (std::ferror) is set and the file position is unaffected.
