C++ (Cpp) CArgDescriptions::AddPositional Examples

Example #1

bool CTestDiagApp::TestApp_Args(CArgDescriptions& args)
{
    args.AddPositional("case_number",
                       "case number",
                       CArgDescriptions::eInteger);

    args.SetConstraint("case_number",
                       new CArgAllow_Integers(1, 47));

    return true;
