Function system_error2::_win32_code_domain::get

static constexpr system_error2::_win32_code_domain const& get();

Constexpr singleton getter. Returns the constexpr win32_code_domain variable.

Variable system_error2::win32_code_domain

constexpr system_error2::_win32_code_domain const win32_code_domain;

(Windows only) A constexpr source variable for the win32 code domain, which is that of GetLastError() (Windows). Returned by _win32_code_domain::get().
