• NdisAllocateNetBufferAndNetBufferList
  Allocates and initializes a NET_BUFFER_LIST structure that is initialized with a pre-allocated NET_BUFFER structure.

• NdisAllocateNetBufferList
  Allocates and initializes a NET_BUFFER_LIST structure from a NET_BUFFER_LIST structure pool.

• NdisAllocateNetBufferListContext
  Allocates more context space in the NET_BUFFER_LIST_CONTEXT structure of a NET_BUFFER_LIST structure.

• NdisAllocateNetBufferListPool
  Allocates a pool of NET_BUFFER_LIST structures.

• NdisAllocateNetBufferMdlAndData
  Allocates a NET_BUFFER structure together with the associated MDL and data.

• NdisAllocateNetBufferPool
  Allocates a pool of NET_BUFFER structures.

• NdisAllocateReassembledNetBufferList
  Reassembles a fragmented NET_BUFFER_LIST structure.

• NdisCopyFromNetBufferToNetBuffer
  Copies data from a source NET_BUFFER structure to a destination NET_BUFFER structure.

• NdisCopyReceiveNetBufferListInfo
  Copies the NET_BUFFER_LIST information.

• NdisCopySendNetBufferListInfo
  Copies the NET_BUFFER_LIST information in a transmit NET_BUFFER_LIST structure.

• NdisFreeCloneNetBufferList
  Frees a NET_BUFFER_LIST structure.

• NdisFreeFragmentNetBufferList
  Frees a NET_BUFFER_LIST structure.

• NdisFreeNetBuffer
  Frees a NET_BUFFER structure that was previously allocated from a NET_BUFFER structure.

• NdisFreeNetBufferList
  Frees a NET_BUFFER_LIST structure that was previously allocated from a NET_BUFFER_LIST structure pool.

• NdisFreeNetBufferListContext
  Releases context space in the NET_BUFFER_LIST_CONTEXT structure of a NET_BUFFER_LIST structure.

• NdisFreeNetBufferListPool
  Frees a NET_BUFFER_LIST structure pool.

• NdisFreeNetBufferPool
  Frees NET_BUFFER structure pools that are created with the NdisAllocateNetBufferPool function.

• NdisFreeReassembledNetBufferList
  Frees a reassembled NET_BUFFER_LIST structure and the associated NET_BUFFER structure and MDL chain.

• NdisGetDataBuffer
  Accesses a contiguous block of data from a NET_BUFFER structure.

• NdisGetNetBufferListProtocolId
  Retrieves the protocol identifier from the NetBufferListInfo member of a NET_BUFFER_LIST structure.

• NdisGetPoolFromNetBuffer
  Obtains the NET_BUFFER structure pool handle that is associated with a specified NET_BUFFER structure.

• NdisGetPoolFromNetBufferList
  Gets the NET_BUFFER_LIST structure pool handle that is associated with a specified NET_BUFFER_LIST structure.

• NdisFreeMdl
  Frees an MDL that was allocated by calling the NdisAllocateMdl function.

• NdisQueryNetBufferPhysicalCount
  Returns the maximum number of physical breaks mapped by the buffer descriptors that are associated with the given NET_BUFFER structure.

• NdisRetreatNetBufferListDataStart
  Increases the used dataspace in all the NET_BUFFER structures in a NET_BUFFER_LIST structure.

• NdisRetreatNetBufferDataStart
  Accesses more used dataspace in the MDL chain of a NET_BUFFER structure.

• NetAllocateMdl
  Allocates an MDL with an associated memory block of a specified size.

• NetFreeMdl
  Frees an MDL that was previously allocated by the NetAllocateMdl function.
