MUD for sending LPC data types using TCP protocol.
STREAM for sending raw data using TCP protocol.
DATAGRAM for using UDP protocol.
int socket_create( int mode, string | function read_callback);
int socket_create( int mode, string | function read_callback, string | function close_callback );
This efun is only available if PACKAGE_SOCKETS is compiled in.
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() call. The close callback 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.
socket_create() returns:
a non-negative descriptor on success.
a negative value indicated below on error.
ERRORS - these are in "socket_err.h"

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