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;
