Detailed Description

A ResultStatus instance is a temporary object to which both error codes and instances status_t can be assigned.
If, once such has been assigned, the result turns out to be a failure, the class will throw an IFail using the last error on the error stack.

ResultCheck ok;
try
{
    //NOTE: No need to check what calls have returned. 
    //      If this is an error, the ResultStatus class will ensure that an exception is thrown.
    ok = callSomeFunction_ReturningAnErrorCode();
    ok = callSomeOtherFunction_ReturningAnErrorCode();
    [...]
}
catch ( const IFail& ifail )
{
    //Handle the exception here
    [...]
}

Note

Prefer usage of ResultStatus, since it can handle both error codes and status_t.
