Description
int
rewind ( int fp)
Sets the file position indicator for fp to the beginning of the
file stream.
If an error occurs, returns 0.
The file pointer must be valid, and must point to a file
successfully opened by fopen().
Note:
If you have opened the file in append ("a") mode, any data you write
to the file will always be appended, regardless of the file position.
See also fseek() and
ftell().
