In general if you are in a port / miniport driver model such as NDIS you
want to use NdisXXX functions. There are cross NDIS / KMDF type drivers,
but they should be used only when needed. So assuming you are working in a
normal NDIS environment use NdisAllocateMemoryWithTagPriority. If you step
through this you will find it calls ExAllocatePoolWithTagPriority.

Subject: [ntdev] ExAllocatePoolWithTagPriority vs
NdisAllocateMemoryWithTagPriority
Hello,
I have seen there are these two functions, which look to do the same thing.
The only difference I see, NdisAllocateMemoryWithTagPriority requires an
NDIS_HANDLE and allocates on NonPagedPool, while
ExAllocatePoolWithTagPriority does not require an NDIS_HANDLE and you can
choose the pool.
Can somebody please tell me what differences there actually are between
them, and what I should prefer?
Also, is there something of Windows Hardware Certification Kit, which, for
an NDIS driver it would issue a problem if ExAllocatePoolWithTagPriority was
used instead?
Thanks!
