CONFIGRET CONFIGMG_Deregister_Arbitrator(REGISTERID id, ULONG ulFlags)
Removes a resource arbitrator. This function is rarely called.
This function deregisters an arbitrator and its resource but is not typically used for this purpose. If an arbitrator is global and registers with a NULL device node, it typically is never deregistered (for example, IO, IRQ, DMA and memory). If the arbitrator is local to a specific device node (for example, a PCMCIA socket), it is called automatically by the ARB_REMOVE arbitrator function when its device node is removed.
