.SH NAME
|
|
getw, putw \- input and output of words (ints)
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #include <stdio.h>
|
|
.sp
|
|
.BI "int getw(FILE *" stream );
|
|
.br
|
|
.BI "int putw(int " w ", FILE *" stream );
|
|
.SH DESCRIPTION
|
|
.BR getw ()
|
|
reads a word (that is, an \fIint\fP) from \fIstream\fP.
|
|
It's provided for compatibility with SVr4.
|
|
We recommend you use
|
|
.BR fread (3)
|
|
instead.
|
|
.P
|
|
.BR putw ()
|
|
writes the word \fIw\fP (that is,
|
|
an \fIint\fP) to \fIstream\fP.
|
|
It is provided for compatibility with SVr4, but we recommend you use
|
|
.BR fwrite (3)
|
|
instead.
|
|
.SH "RETURN VALUE"
|
|
Normally,
|
|
.BR getw ()
|
|
returns the word read, and
|
|
.BR putw ()
|
|
returns 0.
|
|
On error, they return \fBEOF\fP.
|
|
.SH "CONFORMING TO"
|
|
SVr4, SUSv2. Not present in POSIX.1-2001.
|
|
.SH BUGS
|
|
The value returned on error is also a legitimate data value.
|
|
.BR ferror (3)
|
|
can be used to distinguish between the two cases.
|
|
.SH "SEE ALSO"
