hmmm,
Say axis2c api function function foo is
axis2_bool_t foo()
and it is wrapped in c++ function bool bar()


axis2_bool_t
foo(void)
{
    return AXIS2_FALSE;
}

bool bar(void)
{
    std::cout << "In C++ wrapper function \n";
    return foo();
}

Then C++ user experience would be

    bool ret;
    ret = bar();
    if(ret == true)
        std::cout << "Success \n";
    if(ret == false)
        std::cout << "Failure \n";

OK. I agree with you
