Remarks

NWDeRegisterNCPExtension is called by the service-providing NLM applications in conjunction with the NWRegisterNCPExtension function.

When an NCP Extension is registered with the NWRegisterNCPExtension function, the address of the queryData parameter is passed as one of the parameters. The pointer is then initialized to point to a 32-byte area of memory in which the service provider can place data. The queryData parameter is also used as a handle for deregistering the NCP Extension.
