.SH DESCRIPTION
|
2006-02-09 20:24:53 +00:00
|
|
|
\fBgetw\fP() reads a word (that is, an \fIint\fP) from \fIstream\fP. It's
|
2006-08-03 13:57:30 +00:00
|
|
|
provided for compatibility with SVr4. We recommend you use
|
2004-11-03 13:51:07 +00:00
|
|
|
\fBfread\fP(3) instead.
|
|
|
|
.P
|
2006-02-09 20:24:53 +00:00
|
|
|
\fBputw\fP() writes the word \fIw\fP (that is, an \fIint\fP) to \fIstream\fP. It
|
2006-08-03 13:57:30 +00:00
|
|
|
is provided for compatibility with SVr4, but we recommend you use
|
2004-11-03 13:51:07 +00:00
|
|
|
\fBfwrite\fP(3) instead.
|
|
|
|
.SH "RETURN VALUE"
|
2005-10-19 06:54:38 +00:00
|
|
|
Normally, \fBgetw\fP() returns the word read, and \fBputw\fP() returns 0.
|
2004-11-03 13:51:07 +00:00
|
|
|
On error, they return \fBEOF\fP.
|
|
|
|
.SH BUGS
|
|
|
|
The value returned on error is also a legitimate data value.
|
|
|
|
\fBferror\fP(3) can be used to distinguish between the two cases.
