Comment (by psiha):

 AFAICT it should be enough to call NtCreateSection with
 OBJECT_ATTRIBUTES::Attributes
  (http://msdn.microsoft.com/en-us/library/ff557749(VS.85).aspx) set to
 OBJ_PERMANENT...
 Also look into:
 NtMapViewOfSection
 NtMakeTemporaryObject
 NtQuerySection
 NtExtendSection ...

 See http://undocumented.ntinternals.net ...

 Also, sometimes good/better information can be found in driver oriented
 documentation that use the Zw-prefixed functions (e.g.
 http://www.osronline.com/ddkx/kmarch/k111_4oc2.htm) which are equivalent
 to the Nt ones (but for kernel mode code)...

 ps. as mentioned in the original post, I'm willing to help...what I
 primarily want is a no-bloat/STL-uncluttered shared memory/mapped memory
 implementation (i.e. that 'looks' and 'acts' 'C++ kosher' but is
 optimizer-transparent enough so that it compiles to code nearly identical
 as if the OS calls were manually/hand coded, as was demonstrated in the
 post linked to in the trac ticket 4234)...so if you want I can try and
 provide such a collection of lower level layer primitives (that I've, as
 mentioned, already started developing for GIL.IO) which you can then wrap
 as needed...

 pps. this is a fork of the original thread:
