Hi,

Is there any way to associate a filename to an IOServiceOpen call? Is there a way to tell which kernel extension (kext) an IOServiceOpen will open.

Consider the following code:

kernResult = IOServiceGetMatchingServices( kIOMasterPortDefault, IOServiceMatching( "Foo" ), &iterator );

if( kernResult == kIOReturnSuccess ) { service = IOIteratorNext( iterator ); IOObjectRelease( iterator );

if( service ) { kernResult = IOServiceOpen( service, mach_task_self(), 0, &dataPort );

Is there any way to determine the kernel extension that will have its newUserClient method invoked based on the above code? Right now I can grep through plists in /System/Library/Extensions and search for Foo but is there any better way?

Thanks,

David Rose
