Hi,
MSDN is silent about the lifetime of the MIDI/MIXER/WAVEOPENDESC structure
that is deliverred via the W/MODM_OPEN/MXM_OPEN message to the winmm drivers
(WAVEOOPENDESC is not even documented for MS-Windows (not CE) anymore).
http://msdn.microsoft.com/en-us/library/ff537518%28v=vs.85%29.aspx MIDIOPENDESC
IMHO, it would make a lot of sense if the structure remained allocated
for the whole lifetime of the open/close cycle, so the driver need not make a
copy of it.
Is there anybody who knows more about this topic?
I wouldn't count on it, the structure is allocated on the stack, see for
example winmm.c: WAVE_Open
Cheers,
Maarten
