I do not know why microsoft would do this. I think it would have make things easier to know which parameter they took, especially when you have a enum define for something. Then in the structure instead of defining one of the attribute with that enum they pass an Int instead. A good example of that is
enum D3D12_COMMAND_QUEUE_PRIORITY
{
D3D12_COMMAND_QUEUE_PRIORITY_NORMAL = 0,
D3D12_COMMAND_QUEUE_PRIORITY_HIGH = 100
} D3D12_COMMAND_QUEUE_PRIORITY;
typedef struct D3D12_COMMAND_QUEUE_DESC
{
D3D12_COMMAND_LIST_TYPE Type;
INT Priority;
D3D12_COMMAND_QUEUE_FLAGS Flags;
UINT NodeMask;
}
The Priority flag is a D3D12_COMMAND_QUEUE_PRIOORITY why the heck would they pass an Int. I know at the end of the day an enum is just an Int, but it would have been more friendly and i would not need to look at the documentation to make sure that the correct Int values that can be passed are D3D12_COMMAND_QUEUE_PRIORITY. I am pretty sure they have similar issues throughout the API.
