<H2>DESCRIPTION</H2>
|
|
|
|
<B>getw</B>()
|
|
|
|
reads a word (that is, an <I>int</I>) from <I>stream</I>.
|
|
It's provided for compatibility with SVr4.
|
|
We recommend you use
|
|
<B><A HREF="/cgi-bin/man/man2html?3+fread">fread</A></B>(3)
|
|
|
|
instead.
|
|
<P>
|
|
|
|
<B>putw</B>()
|
|
|
|
writes the word <I>w</I> (that is,
|
|
an <I>int</I>) to <I>stream</I>.
|
|
It is provided for compatibility with SVr4, but we recommend you use
|
|
<B><A HREF="/cgi-bin/man/man2html?3+fwrite">fwrite</A></B>(3)
|
|
|
|
instead.

<H2>RETURN VALUE</H2>
|
|
|
|
Normally,
|
|
<B>getw</B>()
|
|
|
|
returns the word read, and
|
|
<B>putw</B>()
|
|
|
|
returns 0.
|
|
On error, they return <B>EOF</B>.
