|
|
* This function converts a 16 bit mci command request into an
|
|
* equiverlant 32 bit request.
|
|
*
|
|
* The ideas behind this function were stolen from ThunkWMMsg16,
|
|
* see wmsg16.c and mciDebugOut see mci.c
|
|
*
|
|
* We return 0 if the thunk was OK, any other value should be used as
|
|
* an error code. If the thunk failed all allocated resources will
|
|
* be freed by this function. If the thunk was sucessful (ie. returned 0)
|
|
* UnThunkMciCommand16 MUST be called to free allocated resources.
|
|
*
|
|
* Here are the assumptions that I have used to perform the thunking:
|
|
*
|
|
* 1. MCI_OPEN is a special case.
|
|
*
|
|
* 2. If the message is NOT defined in mmsystem.h then it is treated as a
|
|
* "user" command. If a user command table is associated with the given
|
|
* device ID we use this command table as an aid to perform the thunking.
|
|
* If a user command table is NOT associated with the device ID the
|
|
* command does NOT GET THUNKED, we return straight away, calling
|
|
* mciSendCommand only to get a relevant error code.
|
|
*
|
|
* 3. If the command IS defined in mmsystem.h we perfrom a "manual" thunk
|
|
* of the command IF the associated PARMS structure contains ReservedX
|
|
* fields. We mask out the associated flags as each field is thunked.
|
|
*
|
|
* 4. If there are any flags left then we use the command table
|
|
* as an aid to perform the thunking.
