KsStudio is a tool included in the WDK for testing kernel streaming drivers. It's a little opaque, but it won't take you long. The center panel is a little bit like graphedt; you drag your driver from a list onto that panel, then instantiate it, then click a pin and instantiate that. There is a detailed log that shows you the ioctl exchange as the negotiation occurs. -- Tim Roberts, timr@xxxxxxxxx Providenza & Boekelheide, Inc. ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
