|
|
|
|

|

|
|
<ALWAYS use the STORExxx macros>
|

|
|
|
|
FREEARGPTR( parg16 );
|
|
RETURN( ul );
|
|
}
|
|
|
|
NOTE:
|
|
|
|
The VDM frame is automatically set up, with all the function parameters
|
|
available via parg16->f<number>.
|
|
|
|
Handles must ALWAYS be mapped for 16 -> 32 -> 16 space via the mapping tables
|
|
laid out in WALIAS.C.
|
|
|
|
Any storage you allocate must be freed (eventually...).
|
|
|
|
Further to that - if a thunk which allocates memory fails in the 32 bit call
|
|
then it must free that memory.
|
|
|
|
Also, never update structures in 16 bit land if the 32 bit call fails.
|
|
|
|
Be aware that the GETxxxPTR macros return the CURRENT selector-to-flat_memory
|
|
mapping. Calls to some 32-bit functions may indirectly cause callbacks into
|
|
16-bit code. These may cause 16-bit memory to move due to allocations
|
|
made in 16-bit land. If the 16-bit memory does move, the corresponding 32-bit
|
|
ptr in WOW32 needs to be refreshed to reflect the NEW selector-to-flat_memory
|
|
mapping.
