Xinput?

I have the following code and get errors and I dont know why:

Code:

---

dword_result_t XamInputGetCapabilities(dword_t user_index, dword_t flags, pointer_t<X_INPUT_CAPABILITIES> caps_ptr) {
  if (!caps_ptr) {
    return X_ERROR_BAD_ARGUMENTS;
    return;
  }
  if ((flags & 0xFF) && (flags & XINPUT_FLAG_GAMEPAD) == 0) {
    // Ignore any query for other types of devices.
    return X_ERROR_DEVICE_NOT_CONNECTED;
    return;
  }
  if ((user_index & 0xFF) == 0xFF || (flags & XINPUT_FLAG_ANY_USER)) {
    // Always pin user to 0.
    user_index = 0;
  }


  auto input_system = kernel_state()->emulator()->input_system();
 
  X_RESULT result = input_system->GetCapabilities(user_index, flags, caps_ptr);
  return result;
}

---

The following errors:

error C2561: 'xe::kernel::xam::XamInputGetCapabilities': func
tion must return a value

error C2678: binary '=': no operator found which takes a left
-hand operand of type 'const xe::kernel::shim::ParamBase<uint32_t>

Now the parameters at this link and I am changing the code from a shim call to dword_result_t

shim_utils.h Source View - Source code download - xenia dword_t I am guessing is wrong for user_index unless I have to do something like user_index.value() = 0;

I would simply delete lines 4 and 9, those empty (and unreachable) return statements without a value.
You return values on the return statements on the preceding lines.

Also, why do this?
X_RESULT result = input_system->GetCapabilities(user_index, flags, caps_ptr);
return result;

When you can do this
return input_system->GetCapabilities(user_index, flags, caps_ptr);

I have most of it working thanks Salem. However, I still get this error:


c:\users\tom\xenia\src\xenia\kernel\xam\xam_input. cc(67): error C2678: binary '=': no operator found which takes a left
-hand operand of type 'const xe::kernel::shim::ParamBase<uint32_t>' (or there is no acceptable conversion)

This is the defined list and I am guessing I have to do something with user_index.

1. using int_t = const shim::ParamBase<int32_t>&;
2. using word_t = const shim::ParamBase<uint16_t>&;
   
3. using dword_t = const shim::ParamBase<uint32_t>&;
   
4. using qword_t = const shim::ParamBase<uint64_t>&;
   
5. using float_t = const shim::ParamBase<float>&;
   
6. using double_t = const shim::ParamBase<double>&;
   
7. using lpvoid_t = const shim::PointerParam&;
   
8. using lpword_t = const shim::PrimitivePointerParam<uint16_t>&;
   
9. using lpdword_t = const shim::PrimitivePointerParam<uint32_t>&;
   
10. using lpqword_t = const shim::PrimitivePointerParam<uint64_t>&;
    
11. using lpfloat_t = const shim::PrimitivePointerParam<float>&;
    
12. using lpdouble_t = const shim::PrimitivePointerParam<double>&;
    
13. using lpstring_t = const shim::StringPointerParam<char, std::string>&;
    
14. using lpwstring_t = const shim::StringPointerParam<wchar_t, std::wstring>&;
    
15. using function_t = const shim::ParamBase<uint32_t>&;
    
16. using unknown_t = const shim::ParamBase<uint32_t>&;
    
17. using lpunknown_t = const shim::PointerParam&;
    
18. template <typename T>
    
19. using pointer_t = const shim::TypedPointerParam<T>&;
    
20. 
    
21. using int_result_t = shim::Result<int32_t>;
    
22. using dword_result_t = shim::Result<uint32_t>;
    
23. using pointer_result_t = shim::Result<uint32_t>;

I am still getting this error and I think need to do something with user_index.

error C2678: binary '=': no operator found which takes a left
-hand operand of type 'const xe::kernel::shim::ParamBase<uint32_t>'

Here is the types list I think:

1. using int_t = const shim::ParamBase<int32_t>&;
2. using word_t = const shim::ParamBase<uint16_t>&;
   
3. using dword_t = const shim::ParamBase<uint32_t>&;
   
4. using qword_t = const shim::ParamBase<uint64_t>&;
   
5. using float_t = const shim::ParamBase<float>&;
   
6. using double_t = const shim::ParamBase<double>&;
   
7. using lpvoid_t = const shim::PointerParam&;
   
8. using lpword_t = const shim::PrimitivePointerParam<uint16_t>&;
   
9. using lpdword_t = const shim::PrimitivePointerParam<uint32_t>&;
   
10. using lpqword_t = const shim::PrimitivePointerParam<uint64_t>&;
    
11. using lpfloat_t = const shim::PrimitivePointerParam<float>&;
    
12. using lpdouble_t = const shim::PrimitivePointerParam<double>&;
    
13. using lpstring_t = const shim::StringPointerParam<char, std::string>&;
    
14. using lpwstring_t = const shim::StringPointerParam<wchar_t, std::wstring>&;
    
15. using function_t = const shim::ParamBase<uint32_t>&;
    
16. using unknown_t = const shim::ParamBase<uint32_t>&;
    
17. using lpunknown_t = const shim::PointerParam&;
    
18. template <typename T>
    
19. using pointer_t = const shim::TypedPointerParam<T>&;
    
20. 
    
21. using int_result_t = shim::Result<int32_t>;
    
22. using dword_result_t = shim::Result<uint32_t>;
    
23. using pointer_result_t = shim::Result<uint32_t>;

I figured it out. Now I have to figure out the keyboard one.
