@class IOMultiMemoryDescriptor : public IOMemoryDescriptor @abstract The IOMultiMemoryDescriptor object describes a memory area made up of several other IOMemoryDescriptors. @discussion The IOMultiMemoryDescriptor object represents multiple ranges of memory, specified as an ordered list of IOMemoryDescriptors. The descriptors are chained end-to-end to make up a single contiguous buffer.
