POSIX_SOCKETS

The POSIX_SOCKETS feature provides a TCP/IP stack through POSIX-compatible socket system calls. For general information on this feature, see intro(2POSIX) and the POSIX draft standard P1003.1g. However, POSIX_SOCKETS only provides support of the AF_INET domain. The AF_LOCAL domain support is provided by the AF_LOCAL feature.

For more details, see POSIX_SOCKETS(5FEA).
