Member Function Documentation

nameInfo() [1/3]

template<typename I = IPv4>

void uvw::GetNameInfoReq::nameInfo	(	Addr	addr,

nameInfo() [2/3]

void uvw::GetNameInfoReq::nameInfo	(	const sockaddr &	addr,
		int	flags = 0
	)

Async getnameinfo.

Parameters

addr	Initialized sockaddr_in or sockaddr_in6 data structure.
flags	Optional flags that modify the behavior of getnameinfo.

nameInfo() [3/3]

template<typename I = IPv4>

void uvw::GetNameInfoReq::nameInfo	(	const std::string &	ip,
		unsigned int	port,
		int	flags = 0
	)
