std::error_code::operator=(3) | C++ Standard Libary | std::error_code::operator=(3) |
NAME¶
std::error_code::operator= - std::error_code::operator=
Synopsis¶
template< class ErrorCodeEnum > (since C++11)
error_code& operator=( ErrorCodeEnum e ) noexcept;
Replaces the error code and corresponding category with those representing
error
code enum e.
Equivalent to *this = make_error_code(e), where make_error_code is called
unqualified to enable argument-dependent lookup. This overload participates
in
overload resolution only if
std::is_error_code_enum<ErrorCodeEnum>::value is true.
Parameters¶
e - error code enum to construct
Return value¶
*this
Notes¶
Copy-assignment operator is defined implicitly.
The ADL-found make_error_code is intended to be used in the original proposal
N2422,
and used by all known implementations. However, the standard requires that
only
std::make_error_code overloads are considered. This is LWG issue 3629.
