A request to rescan a bus for device changes.
- macOS 10.0+
- Mac Catalyst 13.0+
The IOService object to request a rescan, usually obtained via the IOServiceGetMatchingServices or IOServiceAddNotification APIs.
An options mask, interpreted only by the IOService's family.
A return code generated by IOService::requestProbe.
A non kernel client may request a bus or controller rescan for added or removed devices, if the bus family does automatically notice such changes. For example, SCSI bus controllers do not notice device changes. The implementation of this routine is family dependent, and the default IOService implementation returns kIOReturnUnsupported.
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.
