Function Documentation

int XCALL_DEF() x_socket	(	int	domain,
		int	type,
		int	protocol,
		int *	result
	)

Creates an endpoint for communication.

Execution : in-place

Asynchronous failures : abort

Parameters:

[in]	domain	Communication domain; this selects the protocol family which will be used for communication. These families are defined in <sys/socket.h>.
[in]	type	Specifies communication semantics. Currently we support: SOCK_DGRAM: Supports datagrams (connectionless, unreliable messages of a fixed maximum length).
[in]	protocol	Specifies a particular protocol to be used with the socket.
[out]	result	Where to store any asynchronous failures.

Returns:

A new file descriptor for the new socket, or -1 if a synchronous failure occurred (in which case, errno is set appropriately).

Todo:

Implement SOCK_STREAM.
