Detailed Description

Represents an IPv4 address for use with socket functions such as bind().

Avoids type punning with C style casts from sockaddr_in to sockaddr pointers.

Constructor & Destructor Documentation

address_t()

dpp::address_t::address_t	(	const std::string_view	ip = "0.0.0.0",
		uint16_t	port = 0
	)

Create a new address_t.

Parameters

ip	IPv4 address
port	Port number

Note

Leave both as defaults to create a default bind-to-any setting

Member Function Documentation

get_port()

uint16_t dpp::address_t::get_port

(

socket

fd

)

Get the port bound to a file descriptor.

Parameters

fd	File descriptor

Returns

Port number, or 0 if no port bound

get_socket_address()

sockaddr * dpp::address_t::get_socket_address

(

)

Get sockaddr.

Returns

sockaddr pointer

size()

size_t dpp::address_t::size

(

)

Returns size of sockaddr_in.

Returns

sockaddr_in size

Note

It is important the size this returns is sizeof(sockaddr_in) not sizeof(sockaddr), this is NOT a bug but requirement of C socket functions.
