This function releases a block of memory previously allocated with the NdisAllocateMemoryfunction.
VOID NdisFreeMemory( IN PVOID VirtualAddress , IN UINT Length , IN UINT MemoryFlags );
Parameters
- VirtualAddress
- Pointer to the base virtual address of the allocated memory. This address was returned by the NdisAllocateMemoryfunction.
- Length
- Specifies the size, in bytes, of the memory block to be released. This parameter must be identical to the Lengththat was passed to NdisAllocateMemory.
- MemoryFlags
- Specifies 0 or the bitmask originally passed to
NdisAllocateMemoryfor the preceding range; one of the
following:
Value Description 0 Nonpaged system-space memory. NDIS_MEMORY_CONTIGUOUS Physically contiguous memory. NDIS_MEMORY_NONCACHED Noncached memory. This value must be identical to the MemoryFlagsparameter that was passed to NdisAllocateMemory.
Remarks
The parameters passed to this function must be identical to those passed to NdisAllocateMemorywhen the block of memory was allocated. That is, a caller of this function cannot release a subrange of the block that was allocated.
