the ISO C standard. Any conflict between the

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.
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.
