Module Name:
regdesc.hxx
Abstract:
This module contains the declarations for the following
classes: IO_DESCRIPTOR, IO_PORT_DESCRIPTOR,
IO_INTERRUPT_DESCRIPTOR, IO_MEMORY_DESCRIPTOR and
IO_DMA_DESCRIPTOR. The last 4 classes are derived from
the first one.
These classes models an IO_RESOURCE_DESCRIPTOR structure
used in registry data of type REG_RESOURCE_REQUIREMENTS_LIST.
