Hi, I plan on building a virtual driver based on MSVAD. I need this driver to send/receive the audio bufferss to/from my user space application. In addition, this MSVAD should behave as a regular audio driver for all commercial applications like Skype etc. As I understand, I can not use IOCTL in MSVAD. Is there any example that I can use? In addition, how can I synchronize the activity between the driver and my user space application ? Can a share an Even Object between them ? If so, how ? Thanks, Simhi __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
