Detailed Description

Routines to establish socket connection

Function Documentation

◆ socket_recv_timeout()

int socket_recv_timeout	(	int	sock,
		double	sec
	)

Set recv timeout in seconds

◆ socket_send_timeout()

int socket_send_timeout	(	int	sock,
		double	sec
	)

Set recv timeout in seconds

◆ connect_port()

int connect_port	(	const char *	hostname,
		int	port,
		int	block,
		int	nodelay
	)

Connect to a host at port. If hostname already includes port after :, port is ignored. hostname may start with / to indicate a local UNIX port

Parameters

hostname	The hostname can be just name or name:port.
port	The port if hostname does not include it
block	Do we block until connection is established
nodelay	set TCP nodelay flag

◆ listen_port()

void listen_port	(	uint16_t	port,
		char *	localpath,
		int(*)(int)	responder,
		double	timeout_sec,
		void(*)()	timeout_fun,
		int	nodelay
	)

Open a port and listen to it. Calls respond(sock) to handle data. If timeout_fun is not NULL, it will be called when 1) connection is establed/handled, 2) every timeout_sec if timeout_sec>0. This function only return at error. if localpath is not null and start with /, open the local unix port also if localpath is not null and contains ip address, only bind to that ip address

◆ socket_block()

int socket_block	(	int	sock,
		int	block
	)

Set socket to unblocking mode

◆ bind_socket()

int bind_socket	(	int	protocol,
		char *	ip,
		uint16_t	port
	)

make a server port and bind to localhost on all addresses. protocl is usually SOCK_DGRAM or SOCK_STREAM. ip is usually zero. if port is 0, will bind an assigned port

◆ socket_port()

int socket_port ( int sock )

determine the socket port

◆ socket_peer()

in_addr_t socket_peer ( int sock )

determine the socket peer IP address

◆ addr2name()

const char* addr2name ( in_addr_t s_addr )

convert in_addr_t to host name for print out
