 ## **PROTOCOLS**

 ## Provider {#Provider}
 *Defined in [fuchsia.posix.socket.packet/socket.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.posix.socket.packet/socket.fidl;l=223)*
 <p>A packet socket provider.</p>


 ### Socket {#Provider.Socket}

 <p>Requests a packet socket.</p>
 <ul>
 <li>request <code>kind</code> the kind of packet socket to create.</li>
 </ul>
 <ul>
 <li>response <code>socket</code> the packet socket.</li>

 ## Socket {#Socket}
 *Defined in [fuchsia.posix.socket.packet/socket.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.posix.socket.packet/socket.fidl;l=136)*
 <p>A packet socket.</p>
 <p>This interface is essentially POSIX.</p>
 <p>All methods on this type are nonblocking; their exact behaviors match their
 Linux counterparts.</p>
 <p><em>Warning:</em> This protocol is not yet ready for direct use by clients.
 Instead, clients should use the BSD sockets API to interact with sockets.
 We plan to change this protocol substantially and clients that couple
 directly to this protocol will make those changes more difficult.</p>


 ### Bind {#Socket.Bind}

 <p>Bind the socket to a protocol and/or interface.</p>
 <ul>
 <li>request <code>protocol</code> the socket's new protocol association.</li>
 <li>request <code>bound_interface_id</code> the socket's new interface binding.</li>
 </ul>

 </table>


 ### Close {#Socket.Close}

 <p>Terminates the connection.</p>
 <p>After calling <code>Close</code>, the client must not send any other requests.</p>
 <p>Servers, after sending the status response, should close the connection
 regardless of status and without sending an epitaph.</p>
 <p>Closing the client end of the channel should be semantically equivalent
 to calling <code>Close</code> without knowing when the close has completed or its
 status.</p>
