Constructor & Destructor Documentation

CPConnection::CPConnection	(	CBaseSocket *	pOwner,
		struct sockaddr *	pAddr = `NULL`,
		int	iMaxSendBufferSize = `CS_OUTBUFFER_SIZE`
	)

Member Function Documentation

void CPConnection::AsyncTerminateConnection ( ) [virtual]

Asynchronously close the socket. If a handler hasn't been assigned, this calls TerminateConnection. Otherwise, the handler waits until the send buffer is clear and then closes the socket.

Definition at line 314 of file CPConnection.cpp.

BOOL CPConnection::Create	(	int	af,
		int	type,
		int	protocol,
		UINT	nPort = `0`,
		LPCSTR	lpAddr = `NULL`,
		BOOL	bReuse = `FALSE`,
		BOOL	bBind = `TRUE`,
		int	iLinger = `-1`
	)		`[virtual]`

Parameters:

type	Address family. Only tested with AF_INET.
protocol	Stream or datagram (SOCK_STREAM or SOCK_DRAM)
nPort	Usually 0 for inet sockets
lpAddr	Port
bReuse	Inet address in the standard xxx.xxx.xxx.xxx format
bBind	Allow reuse of this socket
iLinger	Default to bind the socket. Not needed if this is the result of an ::accept
