<h1 class="topictitle1">File data transfer—<span class="apiname">send_file()</span> and <span class="apiname">accept_and_recv()</span></h1>
<div><p>i5/OS™ sockets
provide the <span class="apiname">send_file()</span> and <span class="apiname">accept_and_recv()</span> APIs
that enable faster and easier file transfers over connected sockets.</p>
<p> These two APIs are especially useful for file-serving applications such
as Hypertext Transfer Protocol (HTTP) servers.</p>
<p>The <span class="apiname">send_file()</span> enables the sending of file data directly
from a file system over a connected socket with a single API call.</p>
<p>The <span class="apiname">accept_and_recv()</span> is a combination of three socket
functions: <span class="apiname">accept()</span>, <span class="apiname">getsockname()</span>,
and <span class="apiname">recv()</span>. </p>
