Type alias system_error2::_getaddrinfo_code_domain::value_type

using value_type = int;

The value type of the getaddrinfo() code, which is an int

Constructor system_error2::_getaddrinfo_code_domain::_getaddrinfo_code_domain

Default constructor

Function system_error2::_getaddrinfo_code_domain::get

static constexpr system_error2::_getaddrinfo_code_domain const& get();

Constexpr singleton getter. Returns constexpr getaddrinfo_code_domain variable.

Variable system_error2::getaddrinfo_code_domain

constexpr system_error2::_getaddrinfo_code_domain const getaddrinfo_code_domain;

A constexpr source variable for the getaddrinfo() code domain, which is that of getaddrinfo(). Returned by _getaddrinfo_code_domain::get().
