Subject:    Wrong declaration of CRYPT_RETURN_HWND in CSPDK

Hello anyone responsible at Microsoft,

after I found out that the wincrypt.h in the current CSPDK (from June
2001) is newer than the one in the Platform SDK I got, I replaced the
#include <wincrypt.h> with an include for the "SDKINC/wincrypt.h" plus
"SDKINC/cspdk.h".
I had to change some of my function declarations because the prototypes
changed slightly. One change is in the structure VTableProvStruc, where
the FuncReturnhWnd member was a FARPROC before and is now a function
pointer type called CRYPT_RETURN_HWND.
After compiling and testing the new CSP I experienced a crash when
calling that FuncReturnhWnd and I quickly found that FARPROC is declared
as WINAPI, while CRYPT_RETURN_HWND is not. After chaning the declaration
of CRYPT_RETURN_HWND to WINAPI, my provider runs stable again.

My conclusion is: the declaration of CRYPT_RETURN_HWND is wrong.

Can you please fix that for the next release?
Will this "new" wincrypt.h/cspdk.h appear in one of the next Platform
SDKs (and thus spare me some fumbling to include my own version)?

Thanks, Hans
