Member Function Documentation

string Socket::getLocalAddress

(

)

throw (SocketException)

Get the local address

Returns:

local address of socket

Exceptions:

SocketException

thrown if fetch fails

References sockDesc.

unsigned short Socket::getLocalPort

(

)

throw (SocketException)

Get the local port

Returns:

local port of socket

Exceptions:

SocketException

thrown if fetch fails

References sockDesc.

void Socket::setLocalPort

(

unsigned short

localPort

)

throw (SocketException)

Set the local port to the specified port and the local address to any interface

Parameters:

localPort

local port

Exceptions:

SocketException

thrown if setting local port fails

void Socket::setLocalAddressAndPort	(	const string &	localAddress,
		unsigned short	localPort = 0
	)			throw (SocketException)

Set the local port to the specified port and the local address to the specified address. If you omit the port, a random port will be selected.

Parameters:

	localAddress	local address
	localPort	local port

Exceptions:

SocketException

thrown if setting local port or address fails

References fillAddr().

void Socket::cleanUp

(

)

throw (SocketException) [static]

If WinSock, unload the WinSock DLLs; otherwise do nothing. We ignore this in our sample client code but include it in the library for completeness. If you are running on Windows and you are concerned about DLL resource consumption, call this after you are done with all Socket instances. If you execute this on Windows while some instance of Socket exists, you are toast. For portability of client code, this is an empty function on non-Windows platforms so you can always include it.

Parameters:

	buffer	buffer to receive the data
	bufferLen	maximum number of bytes to read into buffer

Returns:

number of bytes read, 0 for EOF, and -1 for error

Exceptions:

SocketException

thrown WinSock clean up fails

unsigned short Socket::resolveService	(	const string &	service,
		const string &	protocol = "tcp"
	)			[static]

Resolve the specified service for the specified protocol to the corresponding port number in host byte order

Parameters:

	service	service to resolve (e.g., "http")
	protocol	protocol of service to resolve. Default is "tcp".
