The RtlIoDecodeMemIoResource routine provides the address information that is contained in an IO_RESOURCE_DESCRIPTOR structure that describes a range of memory or I/O port addresses.
Descriptor [in]A pointer to the IO_RESOURCE_DESCRIPTOR structure to provide the address information for.
Alignment [out, optional]A pointer to a variable that receives the alignment, in bytes, of the address range. This parameter can be NULL.
MinimumAddress [out, optional]A pointer to a variable that receives the minimum address of the address range. This parameter can be NULL.
MaximumAddress [out, optional]A pointer to a variable that receives the maximum address of the address range. This parameter can be NULL.
RtlIoDecodeMemIoResource returns the length of the address range, in bytes.
The Type member of the IO_RESOURCE_DESCRIPTOR structure must be CmResourceTypeMemory, CmResourceTypeMemoryLarge, or CmResourceTypePort.
