int GetInterfaceForNetwork	(	char const *	host_in,
		in_addr &	addr
	)

Convert an IP address to the network address of the interface sharing the subnet mask.

Parameters

	host_in	IP to resolve
[out]	addr	in_addr object populated with resolved host

Returns

0 if success, -1 if gethostbyname fails, 2 if defaulted to 0.0.0.0 (No matching interfaces)

Definition at line 80 of file TCPConnect.hh.

int ResolveHost	(	char const *	host_in,
		in_addr &	addr
	)

Convert a string hostname to a in_addr suitable for socket communication.

Parameters

	host_in	Name or IP of host to resolve
[out]	addr	in_addr object populated with resolved host

Returns

0 if success, -1 if gethostbyname fails

Definition at line 42 of file TCPConnect.hh.

int ResolveHost	(	char const *	host_in,
		int	dflt_port,
		sockaddr_in &	sin
	)

Convert a string hostname and port to a sockaddr_in suitable for socket communication.

Parameters

	host_in	Name or IP of host to resolve
	dflt_port	POrt to populate in output
[out]	sin	sockaddr_in object populated with resolved host and port

Returns

0 if success, -1 if gethostbyname fails

Definition at line 157 of file TCPConnect.hh.

int TCPConnect	(	char const *	host_in,
		int	dflt_port,
		long	flags = 0,
		int	sndbufsiz = 0
	)

Connect to a host on a given port.

Parameters

host_in	Name or IP of the host to connect to
dflt_port	Port to connect to
flags	TCP flags to use for the socket
sndbufsiz	Size of the send buffer. Set to 0 for automatic send buffer management

Returns

File descriptor of connected socket.
