Type alias system_error2::nt_code

using nt_code = status_code<system_error2::_nt_code_domain>;

Type alias system_error2::nt_error

using nt_error = status_error<system_error2::_nt_code_domain>;

(Windows only) A specialisation of status_error for the NT error code domain.

};

(Windows only) The implementation of the domain for NT error codes, those returned by NT kernel functions.

Type alias system_error2::_nt_code_domain::value_type

using value_type = 'hidden';

The value type of the NT code, which is a win32::NTSTATUS

Constructor system_error2::_nt_code_domain::_nt_code_domain

constexpr _nt_code_domain(typename _base::unique_id_type id = 0x93f3b4487e4af25b) noexcept;

Default constructor

Function system_error2::_nt_code_domain::get

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

Constexpr singleton getter. Returns the constexpr nt_code_domain variable.

Variable system_error2::nt_code_domain

constexpr system_error2::_nt_code_domain const nt_code_domain;

(Windows only) A constexpr source variable for the NT code domain, which is that of NT kernel functions. Returned by _nt_code_domain::get().
