.SH DESCRIPTION
|
|
|
|
.LP
|
|
|
|
The call:

.RE
|
|
|
|
.LP
|

shall be equivalent to:
|
|
|
|
.sp
|
|
|
|
.RS
|
|

.RE

|
.LP
|
|
|
|
except that \fIrewind\fP() shall also clear the error indicator.
|
|
|
|
.LP
|
|
|
|
Since \fIrewind\fP() does not return a value, an application wishing
|
|
|
|
to detect errors should clear \fIerrno\fP, then call
|
|
|
|
\fIrewind\fP(), and if \fIerrno\fP is non-zero, assume an error has
|
|
|
|
occurred.
|
|
|
|
.SH RETURN VALUE
|
|
|
|
.LP
|
|
|
|
The \fIrewind\fP() function shall not return a value.
|
|
|
|
.SH ERRORS
|
|
|
|
.LP
|
|
|
|
Refer to \fIfseek\fP() with the exception of [EINVAL] which does not
|
|
|
|
apply.
