I am a newbie in kernel-streaming topics and the drivers... All I need is to play a midi-note in windows kernel-mode. Like MidiOutShortMessage in WinAPI. Where can I read the manuals or examles? Must I use IMiniport interfaces or create complex streams? But how to use this IMiniport interfaces I don't understand completely. All I understand now is to find some PortMidi in system, create a new stream in his Mimiport and to write data. But I don't knpw how to find this Port. I think, there is no need in creating new port. Can you give me code-examples or even ready code? It is easier to understand topics with examples. I must implement this in coming days, it is my home task in university. ****************** 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/
