Module Name:

	fsd_dtp.c

Abstract:

	This module contains the entry points for the AFP desktop APIs. The API
	dispatcher calls these. These are all callable from FSD. All of the APIs
	complete in the DPC context. The ones which are completed in the FSP are
	directly queued to the workers in fsp_dtp.c
