I can't think of a reason why anyone would use these. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Robert Bielik Sent: Monday, February 13, 2012 9:43 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] 32 bit structs ? Ooops, I just encountered several dually defined structs for communicating with WaveRT device drivers: KSRTAUDIO_BUFFER_PROPERTY vs. KSRTAUDIO_BUFFER_PROPERTY32 KSRTAUDIO_BUFFER_PROPERTY_WITH_NOTIFICATION vs. KSRTAUDIO_BUFFER_PROPERTY_WITH_NOTIFICATION32 ... and I am now worried that the failure to use the ******32 structs will be problematic sometimes (the implementation in question is the Portaudio WDM/KS implementation). Could someone knowledgeable line up where and why I should be using ******32 structs instead of their counterpart ?
