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.
