Firstly a quick note: I have opened a bug for implementation of wintab.dll (Bug No. 1160)
Now the questions:
1: Writing stubs. I'll be taking up Patrik Stridvall's offer to write stubs for anyone new to wine development.
Yes, I'm working on it right now. Will probably not finish tonight though.
One question about stubs: What's the wine policy on stub return values?
No general policy. It depends.
Should a stub always return an error?
Normally stubs should indicate error (return NULL, FALSE or similar) and do SetLastError(ERROR_NOT_IMPLEMENTED).
Should/Can it return success?
In some cases indicating success (return TRUE or similar), even though it not strictly correct, might be a good idea. It depends.
Lying to the application should be avoided of course but sometimes it is nessary.
2: Testing wintab.dll in Win98. wintab.dll is quite complex for what it does.
I guess you mean wintab32.dll. wintab.dll is the 16 bit variant AFAICS.
Therefore the only practical way to implement it is to work on the functions and communication models that are used by the apps I want it to support.
Probably.
To do this, I need some tool that can log the function calls and parameters to the DLL, while wunning Win98.The logging must be able to let the programmer choose elements from data stuctures in parameters/retvals to log. Any ideas????
There are no good tools to do this AFAIK. But if you find any I'm very intrested.
I've attempted to use apis32 and built a wintab.fnl file for wintab.dll. Unfortunately apis32 doen't allow the logging of the contents of data structs.
Yes. APIS32 is the best AFAIK and it sucks pretty bad IMHO.
I would also like to know experinces with Spy++. Wintab can send it's own custom messages, so I'm wondering how good Spy++ is at detecting custom messages?
I've used it many times before, but only to examine standard windows messages.
No idea, haven't used it for years.
3: Coding standards. I haven't found any coding standards associated with wine. This is particularly important, as I'll be writing new source files. Can someone point me to the standards?
We have none. Decide for yourself. However please do not choose anything to unlik anything else in Wine.
