Hello,
 
 I have created a memory heap in the init_module routine of a kernel module : 
 rt_heap_create(&heap_data,"RT_LOG_HEAP",sizeof(ttv_log_data),H_FIFO|H_SHARED);
 and 
 rt_heap_alloc(&heap_data,0,TM_NONBLOCK,&loc_ptr);
 Both calls return succesful.
 
 When i try to bind to this memory in an user space application :
 rt_heap_bind(&rt_heap,"RT_LOG_HEAP",TM_NONBLOCK);
 the call returns with error -2, this error does not seem to be documented (i test on all the constants defined in the html API docs, xenomai v2.0).
 
 Can anyone give me a hint on what's wrong here ?
 
 Cedric.
