REWIND(3P)

PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

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.

The following sections are informative.

EXAMPLES

None.

APPLICATION USAGE

None.

RATIONALE

None.

FUTURE DIRECTIONS

None.
