socket_create() - create an efun socket
#include <socket_err.h> int socket_create( int mode, string read_callback, void | string close_callback );
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 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.
