dwFlags

Specifies the properties of the mapped memory. By default, the properties of the mapped view of the memory are read/write, cache enabled, write-back caching policy. This parameter allows modifying some of the default properties. Possible flags include:

PTE_WRITE_THRU	Enables write-through caching policy for the mapped memory.
PTE_CACHE_DISABLE	Disables caching for the mapped memory.
PTE_PAT	Allows setting the PAT bit to index the desired PAT entry to select caching policy for the mapped memory.

cbByteCount

The size in bytes of the area to be mapped.

paBlock

The ??.
