Initiates a connection using the socket descriptor socket, which must be a valid socket descriptor created with socket_create().
The address parameter is either an IP address in dotted-quad notation (e.g. 127.0.0.1), if the socket is of the AF_INET family; or the pathname of a Unix-domain socket, if the socket family is AF_UNIX.
The port parameter is only used when connecting to an AF_INET socket, and designates the port on the remote host to which a connection should be made.
Returns zero on success, or a negative error code on failure. This code may be passed to socket_strerror() to get a textual explanation of the error.
See also socket_bind(), socket_listen(), socket_create(), socket_get_status(), and socket_strerror().
