Function Documentation

currentErrorCode()

auto xentara::utils::eh::currentErrorCode ( ) -> std::error_code

noexcept

Returns an error code for the current exception.

This function returns an error code that describes the current exception, as retuned by std::current_exception(). If the current exception is derived from std::system_error, the corresponding error is returned. Otherwise, a custom error code is returned.

A custom error code is also returned for system errors containing an error code with error number 0.

If there is no current exception, std::error_code() is returned.

Returns

An error code describing the current exception, or std::error_code() for none.
