PROLOG

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

NAME

13       rewind — reset the file position indicator in a stream
14

SYNOPSIS

16       #include <stdio.h>
17
18       void rewind(FILE *stream);
19

DESCRIPTION

21       The functionality described on this reference page is aligned with  the
22       ISO C  standard.  Any  conflict between the requirements described here
23       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
24       defers to the ISO C standard.
25
26       The call:
27
28           rewind(stream)
29
30       shall be equivalent to:
31
32           (void) fseek(stream, 0L, SEEK_SET)
33
34       except that rewind() shall also clear the error indicator.
35
36       Since  rewind()  does  not  return  a  value, an application wishing to
37       detect errors should clear errno, then call rewind(), and if  errno  is
38       non-zero, assume an error has occurred.
39

RETURN VALUE

41       The rewind() function shall not return a value.
42

ERRORS

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