- address UIntPtr
-
A pointer to the base address of the region of pages to be queried.
This value is rounded down to the next page boundary.
To determine the size of a page on the host computer, use the GetSystemInfo function.
- refBuffer MemoryBasicInformation32
-
A pointer to a MemoryBasicInformation32 structure in which information about the
specified page range is returned.
- length IntPtr
-
The size of the buffer pointed to by the lpBuffer parameter, in bytes.
IntPtr
The return value is the actual number of bytes returned in the information buffer
If the function fails, the return value is 0.
