NAME
       socket - creates a socket.

SYNOPSIS
       #include <sys/socket.h>

       int socket(int domain, int type, int protocol);

DESCRIPTION
       socket() creates a socket in the specified domain. A socket is a commu‐
       nications endpoint. Currently two  values  are  supported  for  domain,
       PF_INET for internet sockets and PF_UNIX for local unix domain sockets.
       The type of socket can be SOCK_STREAM for TCP sockets  in  the  PF_INET
       domain or SOCK_DGRAM for UDP sockets in the PF_INET domain. For sockets
       in the PF_UNIX domain, SOCK_STREAM, SOCK_DGRAM, and SOCK_SEQPACKET  are
       supported  values  for  type.  The  value  of  protocol	is always 0 or
       IPPROTO_TCP for TCP sockets or IPPROTO_UDP for UDP sockets.

RETURN VALUES
       On success, this function returns  a  numeric  socket  descriptor.   On
       error, -1 is returned and errno is set.

ERRORS
       [EAFNOSUPPORT] The domain is not supported.

       [EPROTOTYPE]   The protocol is not supported by the domain.

       [EMFILE]	      The process descriptor table is full.

       [ENFILE]	      The system descriptor table is full.

       [ENOSPC]	      Could not allocate a file descriptor.
