[Xenomai] rt_sem_create problem

[yogesh garg]

Hi,
I want to protect my shared data structure in my kernel module. But when I
am
trying to call rt_sem_create(), my module makes system hang. Without
rt_sem_create()
call my code works fine.
Please help me whats the problem with rt_sem_create().

Code:-
    RT_SEM mysem;
  ret = rt_sem_create(mysem,"dsem",1,S_PRIO);
  printk(" Return value of sem_create : %d \n",ret);

ret value is success(0).

This is probably not your actual code, but rather some kind of 
pseudo-code, so don't expect much insight. Except perhaps that you 
should pay attention to the compiler warning such code must have produced.
