It is a good question.
Microsoft redefines them, so I would like to add them as part of mapping table,
`HungarianNotationTable`. That means the map include primitive types and
partial windows data types.
```
// Windows Data Type
{"BOOL", "b"}, // typedef int BOOL;
{"BOOLEAN", "b"}, // typedef BYTE BOOLEAN;
{"BYTE", "by"}, // typedef unsigned char BYTE;
{"WORD", "w"}, // typedef unsigned short WORD;
{"DWORD", "dw"}, // typedef unsigned long DWORD;
```
The result will like the following,
```
WORD wVid = 0x8086;
DWORD dwVidDid = 0x80861234;
```

OK~ I will add them. Thank you. The `void*` and `ptrdiff_t` starts with `p`.

Nice consideration, thank you. I will add the feature. function pointers will
start with `fn`.
I will add a test like this,
```
typedef void (*FUNC_PTR_HELLO)();
FUNC_PTR_HELLO Hello = NULL;
// CHECK-MESSAGES: :[[@LINE-1]]:16: warning: invalid case style for variable
'Hello' [readability-identifier-naming]

Make sense. If it was you, will you check it at the caller or in the callee?
and could I know the reason?

Agree with you consideration.
1. I will add more detail about the table, `HungarianNotationTable` .
2. I would like treat it as a default table for this moment. Because I don't
know does it make sense that make user can customized it in `.clang-tidy` file.
The priority in config is higher than default table. Show my idea as the
following,
```
Checks: '-*,readability-identifier-naming'
CheckOptions:
- { key: readability-identifier-naming.VariableCase ,
value: szHungarianNotion }
- { key: readability-identifier-naming.HungarianWordList.uint8 ,
value: u8 }
- { key: readability-identifier-naming.HungarianWordList.uint16 ,
value: u16 }
- { key: readability-identifier-naming.HungarianWordList.uint32 ,
value: u32 }
- { key: readability-identifier-naming.HungarianWordList.uint64 ,
value: u64 }
- { key: readability-identifier-naming.HungarianWordList.unsigned_long,
value: ul }
- { key: readability-identifier-naming.HungarianWordList.long_long ,
value: ll }
```
How about it?

OK, make sense. I will fix it later. Thank you.
