NDIS drivers call the NdisAllocateMemoryWithTagPriority function to allocate a pool of memory from the non-paged pool.
PVOID NdisAllocateMemoryWithTagPriority( NDIS_HANDLE NdisHandle, UINT Length, ULONG Tag, EX_POOL_PRIORITY Priority );
An NDIS handle that the caller obtained during initialization. For example, a miniport driver can use the NDIS handle that it obtained from the NdisMRegisterMiniportDriver or MiniportInitializeEx function. Other NDIS drivers can use the handles from the following functions:
The size to be allocated, in bytes.
A string, delimited by single quotation marks, with up to four characters, usually specified in reversed order. The NDIS-supplied default tag for this call is 'maDN', but the caller can override this default by supplying an explicit value.
The importance of this request. For more information, see ExAllocatePoolWithTagPriority.
NdisAllocateMemoryWithTagPriority returns a pointer to a base virtual address of the allocated memory, or NULL if sufficient nonpaged memory is currently unavailable.
