Shared memory applications are really operating system dependant so you 
will need to read your operating system manuals to work out how to do it.

If you are using a (substantially) POSIX compliant Unix then you might 
want to check out the manual pages for:

shm_open
mmap
ftruncate
munmap
shm_unlink
close

These should give you an idea of how you would link C/C++ programs using 
shared memory. You could then get hold of the Ada POSIX bindings 
(Florist) and then either build them using GNAT, or use them as a basis 
for creating your own application (all you're really doing is importing 
some of the C functions and putting a wrapper round it).

My advice would be to make sure you can get two very simple C/C++ 
programs communicating and then effectively convert one of them into Ada!

Hope this helps.
