Hi all,

I am using the rt_sem_p and rt_sem_v API's in my semaphore application. What
i would like to know is whether the API rt_sem_p is a blocking call or not?
Reasons being when i use it in my code the task does not block when it
encounters rt_sem_p ?

Thanks,

Preetam

Check http://www.xenomai.org/index.php/API_documentation

If you are unsure what the state your your semaphore is before calling
rt_sem_p, have a look at rt_sem_inquire().
