NAME

rewind - reset the file position indicator in a stream

SYNOPSIS

#include <stdio.h>

void rewind(FILE *stream);


DESCRIPTION

^[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.

The call:

rewind(stream)

shall be equivalent to:

(void) fseek(stream, 0L, SEEK_SET)

except that rewind() shall also clear the error indicator.

^[CX] 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

^[CX] Refer to fseek() with the exception of [EINVAL] which does not apply.

EXAMPLES

None.
