NdisAllocateFromBlockPool allocates memory from a block of memory pool.
- BlockPoolHandle [in]
Handle to the block to allocate from.
Returns a buffer if one can be allocated from the block; otherwise, it returns NULL.
NdisAllocateFromBlockPool causes the driver-supplied initialization functionif it is suppliedto run once. This initialization function becomes associated with the block handle after NdisCreateBlockPool is called. The following describes the syntax of the driver-supplied initialization function:
VOID (__stdcall *NDIS_BLOCK_INITIALIZER) ( IN PUCHAR Block, IN SIZE_T NumberOfBytes );
The NdisFreeToBlockPool function is called to release memory back to the block.
