// While std::error_code works OK on all platforms we use, there are some
|
|
// some problems with std::errc that can be avoided by using our own
|
|
// enumeration:
|
|
//
|
|
// * std::errc is a namespace in some implementations. That means that ADL
|
|
// doesn't work and it is sometimes necessary to write std::make_error_code
|
|
// or in templates:
|
|
// using std::make_error_code;
|
|
// make_error_code(...);
|
|
//
|
|
// with this enum it is safe to always just use make_error_code.
|
|
//
|
|
// * Some implementations define fewer names than others. This header has
|
|
// the intersection of all the ones we support.
|
|
//
|
|
// * std::errc is just marked with is_error_condition_enum. This means that
|
|
// common patterns like AnErrorCode == errc::no_such_file_or_directory take
|
|
// 4 virtual calls instead of two comparisons.
