Create a path for a registry entry.
- macOS 10.0+
- UIKit for Mac 13.0+Beta
The registry entry handle whose path to look up.
The name of an existing registry plane. Plane names are defined in IOKitKeys.h, eg. kIOServicePlane.
A char buffer allocated by the caller.
IORegistryEntryGetPath will fail if the entry is not attached in the plane, or if the buffer is not large enough to contain the path.
The path for a registry entry is copied to the caller's buffer. The path describes the entry's attachment in a particular plane, which must be specified. The path begins with the plane name followed by a colon, and then followed by '/' separated path components for each of the entries between the root and the registry entry. An alias may also exist for the entry, and will be returned if available.
Create a matching dictionary that specifies an IOService match based on BSD device name.
Creates and returns a mach port suitable for receiving IOKit messages of the specified type.
Returns the mach port used to initiate communication with IOKit.
Creates and returns a notification object for receiving IOKit notifications of new devices or state changes.
Returns kernel retain count of an IOKit object. Identical to IOObjectGetKernelRetainCount() but available prior to Mac OS 10.6.
Checks two object handles to see if they represent the same kernel object.
Retains an object handle previously returned by IOKitLib.
Look up registered IOService objects that match a matching dictionary, and install a notification request of new IOServices that match.
Close a connection to an IOService and destroy the connect handle.
Create a matching dictionary that specifies an IOService class match.
