ZwCreateSection

Hi, I’m using “ZwCreateSection” but I get an error code that indicates that the 6th parameter is invalid. This parameter is AllocationAttributes, I set this to (SEC_FILE | SEC_COMMIT) as the Nagar’s book says. How do I have to set this parameter?
Thanks.

status = ZwCreateSection(&Section, SECTION_MAP_READ |
SECTION_MAP_WRITE,
NULL, &size, PAGE_READWRITE, SEC_COMMIT, File);

In spite of the documentation (and common sense), you must not specify
SEC_FILE. Just SEC_COMMIT. The documentation states that SEC_FILE gets
implied if you set the final paramter to a non-zero value, and this does
indeed seem to be the case.

Try just SEC_COMMIT.

Yes, it is the case, but it worked when I set it to SEC_COMMIT, but what did
not work was the ZwMapViewOfSection.
Thanks. Well, i’m trying to avoid using file mapping.
