NDIS drivers call the NdisAllocateMemoryWithTagPriority function to allocate a pool of memory from the non-paged pool.
NdisHandle [in]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:
Length [in]The size to be allocated, in bytes.
Tag [in]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.
Priority [in]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.
To free memory that was allocated with NdisAllocateMemoryWithTagPriority, call the NdisFreeMemoryWithTagPriority or NdisFreeMemory function.
