Module Name:
regdesc.hxx
Abstract:
This module contains the declarations for the following base classes:
PARTIAL_DESCRIPTOR, PORT_DESCRIPTOR, INTERRUPT_DESCRIPTOR, MEMORY_DESCRIPTOR,
DMA_DESCRIPTOR and DEVICE_SPECIFIC_DESCRIPTOR. The last 5 classes are derived
from the first one.
These classes model a CM_PARTIAL_RESOURCE_DESCRIPTOR structure, used on registry
data of type REG_FULL_RESOURCE_DESCRIPTOR and REG_RESOURCE_LIST.
