Writing vxd's for Win9x in C

NTDEV
1

Iam writing a pointer port driver for windows Me. Now all the samples given
in DDK are written is assembly. Can’t i write the mouse mini driver in C?

In that case how can i include the asm header files in my .c file? And how
can use the assembly macros defined in vmd.inc?

Thanks
Sesha.

If you write a VXD in C, you don’t need to use asm macros. You should use
VXD-functions wrappers from vxdwraps.clb library. Prototypes of these
wrappers are defined in VXDWRAPS.H file. More over, you can write your own
wrappers which are absent in the original wrapper library.

Yes, this asm include file doesn’t have a corresponding C header file, but
if you prefer to write your VXD in C you can convert it to H-file and then
write your own wrappers of VMD services (which you actually need) as inline
functions (see for instance VMM.H). Almost all VXD wrappers in DDK have
inline and ordinary function versions.

It is amazing how people come to this list before they do ANY research
for themselves.

Well, a more expensive alternative would be to get
VToolsD. They come included with C wrappers for
just about everything. It would help to alleviate
a lot of the menial work involved.

Hi Jamey,
Its equally amazing for me how you came to a conclusion that I
haven’t done ANY research for myself before asking the Q.

I would have appreciated your unsolicited feedback had you given me
some answer or some reference :slight_smile:

BTW iam new to device drivers and very new to VXD’s. Do you still
think i am not eligible for posting such Q’s? :frowning:

Jamey is right.
This is because if you had looked CAREFULLY into the DDK then you could have been found .H files that provide most of the definitions in C syntax that can be found in the .inc files. Furthermore, there is an example of a VxD written in C and a C wrapper library.
