<h4><a name="tag_13_33_03"></a>DESCRIPTION</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i><netinet/tcp.h></i> header shall define the following macro for use as a socket option at the IPPROTO_TCP
|
|
level:</p>
|
|
|
|
<dl compact>
|
|
<dt>TCP_NODELAY</dt>
|
|
|
|
<dd>Avoid coalescing of small segments.</dd>
|
|
</dl>
|
|
|
|
<p>The macro shall be defined in the header. The implementation need not allow the value of the option to be set via <a href=
|
|
"../../functions/setsockopt.html"><i>setsockopt</i>()</a> or retrieved via <a href=
|
|
"../../functions/getsockopt.html"><i>getsockopt</i>()</a>.</p>
