rewind(3p)
NAME
rewind - reset the file position indicator in a stream
SYNOPSIS
#include <stdio.h> void rewind(FILE *stream);
DESCRIPTION
- The call:
- rewind(stream)
- shall be equivalent to:
(void) fseek(stream, 0L, SEEK_SET)- except that rewind() shall also clear the error indicator.
- Since rewind() does not return a value, an application wishing to detect errors should clear errno, then call rewind(), and if errno is non-zero, assume an error has occurred.
RETURN VALUE
The rewind() function shall not return a value.
ERRORS
Refer to fseek() with the exception of [EINVAL] which does not apply.
