rewind

Synopsis

#include <stdio.h>

void rewind(FILE *stream);

Status

Partially implemented

Conformance

IEEE Std 1003.1-2017

Description

rewind() - reset the file position indicator in a stream

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() except EINVAL which does not apply.

Tests

Untested
