Re: willTerminate() vs message (kIOMessageServiceIsTerminated)

Title: Re: willTerminate() vs message (kIOMessageServiceIsTerminated)
Dan,

Yes, the provider is closed. The same code gets run in both routines. If I have willTerminate() enabled, then I comment out the kIOMessageServiceIsTerminated message. If I have kIOMessageServiceIsTerminated enabled then I comment out the willTerminate() routine. In the kIOMessageServiceIsTerminated case, my stop() routine gets called by the ioKit. In the willTerminate() case, it doesn’t get called.

Do you close the provider in your willTerminate()
