Shared Memory Usage Example

[Jacques Amar]

I am using apr in a non httpd application. I would like to use a shared 
memory area to pass information between two different standalone 
programs, so I need the shmem to be named. I am trying NOT to resort to 
the built-in Linux shmget. Can anyone point a code example of this being 
 done properly. My current example gives me an error 17 => File Exists.

Thanks
