PIPSocket::Address::Address ( DWORD dw )

Create an IPv4 address from a four byte value in network byte order.

PIPSocket::Address::Address ( const in_addr & addr )

Create an IPv4 address from an in_addr structure.

PIPSocket::Address::Address	(	const int	ai_family,
		const int	ai_addrlen,
		struct sockaddr *	ai_addr
	)

Create an IP (v4 or v6) address from a sockaddr (sockaddr_in, sockaddr_in6 or sockaddr_in6_old) structure.

Member Function Documentation

PString PIPSocket::Address::AsString	(	bool	bracketIPv6 = `false`,
