Hi everyone,

Using the native skin, I have two heaps that I create in a kernel module 
using rt_heap_create.  They are of type H_SHARED.  I can see these in 
the /proc file system.  When I cat these files I get...

bash-2.05b# cat 
/proc/xenomai/registry/native/heaps/header                                                                                      

type=shared:size=8192:used=8192
bash-2.05b# cat /proc/xenomai/registry/native/heaps/uframe
type=shared:size=538624:used=536576

so I know they exist.

Now, in my user space code, I am trying to use these shared memory 
segments by first calling rt_heap_bind to get the uniform descriptor to 
use in a subsequent rt_heap_alloc call, but the bind fails with an 
errorcode of -2 which doesn't map to the return codes listed in the 
documentation.

Any clues?

Am I using the correct calling sequence from user space?
