If I use 1 byte pointer to allocate more than 1 byte space,
could it have problem when free the space ?
I mean, does system know how many bytes should be free ?

For example:
////////////////////////////////////////////////////////////////////////////
////////////////////////
PUCHAR buffer;

buffer = ExAllocatePool(NonPagedPool, sizeof(struct DATA));
// do something
ExFreePool(buffer);
////////////////////////////////////////////////////////////////////////////
////////////////////////

Or, pointer must the same structure as allocate size ?
