NAME
socket_create() - create an efun socket
SYNOPSIS
#include
#include
int socket_create(int mode, string read_callback,
string|void close_callback)
DESCRIPTION
socket_create() creates an efun socket. mode determines
which type of socket is created. Currently supported socket
modes are:
MUD - for sending LPC data types using TCP protocol.
STREAM - for sending raw data using TCP protocol.
DATAGRAM - for using UDP protocol.
The argument read_callback is the name of a function for the
driver to call when the socket gets data from its peer. The
read callback should follow this format:
void read_callback(int fd, mixed message)
Where fd is the socket which received the data, and message
is the data which was received.
The argument close_callback is the name of a function for
the driver to call if the socket closes unexpectedly, i.e.
not as the result of a socket_close(3) call. The close call-
back should follow this format:
void close_callback(int fd)
Where fd is the socket which has closed. NOTE:
close_callback is not used with DATAGRAM mode sockets.
RETURN VALUES
socket_create() returns:
a non-negative descriptor on success.
a negative value indicated below on error.

EESOCKET Problem creating socket.
EESETSOCKOPT Problem with setsockopt.
EENONBLOCK Problem setting non-blocking mode.
