The MmFreeContiguousMemorySpecifyCache routine frees a buffer that was allocated by an MmAllocateContiguousMemorySpecifyCacheXxx routine.
BaseAddress [in]Specifies the base address of the buffer to be freed. Must match the address returned by the MmAllocateContiguousMemorySpecifyCacheXxx call that allocated the buffer.
NumberOfBytes [in]Specifies the size in bytes of the buffer to be freed. Must match the size requested when the buffer was allocated by the MmAllocateContiguousMemorySpecifyCacheXxx routine.
CacheType [in]Specifies the cache type of the buffer to be freed. Must match the cache type requested when the buffer was allocated by the MmAllocateContiguousMemorySpecifyCacheXxx routine.
The MmFreeContiguousMemorySpecifyCache routine frees a block of physically contiguous memory that was allocated by a previous call to the MmAllocateContiguousMemorySpecifyCache or MmAllocateContiguousMemorySpecifyCacheNode routine. However, MmFreeContiguousMemory is the preferred routine to use to free memory that was allocated by an MmAllocateContiguousMemorySpecifyCacheXxx routine. MmFreeContiguousMemory is faster than MmFreeContiguousMemorySpecifyCache and requires fewer parameters.
