Thunking of compman APIs
|
|
|
|
Functions:
|
|
|
|
ICInstall is NOT supported from 16-bit to 32-bit
|
|
|
|
ICRemove is also NOT supported
|
|
|
|
ICInfo - tries the 32-bit side first
|
|
|
|
Handles
|
|
|
|
Are pointers to the PIC table.
|
|
|
|
The 16-bit side handle manager will store these and call us back
|
|
with our 32-bit handles so the thunking routines here receive
|
|
real 32-bit handles.
|
|
|
|
There is NO handle cleanup (why not ???) on task termination
|
|
|
|
/*
|
|
* Make sure the compiler doesn't think it knows better about packing
|
|
* The 16-bit stack is effectively pack(2)
|
|
*/
|
|
|
|
#pragma pack(2)
|
|
|
|
/*
|
|
* Note that everything is in the reverse order to keep with the PASCAL
|
|
* calling convention on the other side
