Hello!
SaHpi.h defines aHpiSensorEventMasksGet() as:
saHpiSensorEventMasksGet(
IN SessionId,
IN ResourceId,
IN SensorNum,
OUTNN *AssertEventMask,
OUTNN *DeassertEventMask
);
So a user provides pointers to assert/deassert mask and Base library fills
it.
I've found that saHpiSensorEventMasksGet() marshalling request
includes that AssertEventMask and DeassertEventMask data.
It means that assert/deassert mask variables provided by user are sent to
daemon along with session id, resource id and sensor num.
And 5 parameters are sent in request instead of 3 needed.
But output parameters are not to be sent in request.
They shall be obtained from the response.
Fortunatelly Base Library and Daemon use the same marshalling code.
Daemon gets these 5 params and uses only 3 of them.
It raises a question:
The backward binary compatibility will be broken if we fix it.
Combination of new Base Lib and Old daemon will crash.
Shall we fix it?
