- @param [in] domain Select the family of protocols for the client or server

- <ul>
- <li>AF_INET - Version 4 UEFI network stack</li>

- @param [in] type Specifies how to make the network connection. The following values
- are supported:
- <ul>
- <li>
- SOCK_DGRAM - Connect to UDP, provides a datagram service that is
- manipulated by recvfrom and sendto.
- </li>
- <li>
- SOCK_STREAM - Connect to TCP, provides a byte stream
- that is manipluated by read, recv, send and write.
- </li>
- <li>
- SOCK_RAW - Connect to IP, provides a datagram service that
- is manipulated by recvfrom and sendto.
- </li>
- </ul>
-
- @param [in] protocol Specifies the lower layer protocol to use. The following
- values are supported:
- <ul>
- <li>IPPROTO_TCP</li> - This value must be combined with SOCK_STREAM.</li>
- <li>IPPROTO_UDP</li> - This value must be combined with SOCK_DGRAM.</li>
- <li>0 - 254</li> - An assigned
