PATH
FindDriversForDevice finds the driver from a file and from a device tree property that represents the "best" driver for a device--that is, the latest version of the most appropriate driver, regardless of whether it is file-based or property-based. The algorithm for determining the best driver is described in Matching Drivers With Devices.
OSErr FindDriversForDevice(
RegEntryIDPtr device,
FSSpec *fragmentSpec,
DriverDescription *fileDriverDesc,
Ptr *memAddr,
long *length,
StringPtr fragName,
DriverDescription *memDriverDesc);
Given a pointer to the RegEntryID value of a device, FindDriversForDevice finds the most suitable driver for that device. If the driver is located in a file, it returns a pointer to the driver's file system specification in fragmentSpec and a pointer to its driver description in fileDriverDesc. If the driver is a fragment located in memory, FindDriversForDevice returns a pointer to its address in memAddr, its length in length, its name in fragName, and a pointer to its driver description in memDriverDesc. FindDriversForDevice initializes all outputs to nil before searching for drivers.
The fragName parameter that FindDriversForDevice returns can be passed to GetDriverMemoryFragment or GetDriverDiskFragment.
