Hi all,

my question is about the right way to lock and inquire a mutex. At time, my code looks like this:


rt_mutex_inquire(&mutex,TM_NONBLOCK);

if(info.lockcnt == 0) 
{
      rt_mutex_lock(&write_mutex,TM_NONBLOCK);

      // do sth.

      rt_mutex_unlock(&mutex);
}


What happens if anyone locks the mutex between my "rt_mutex_inquire(...)" and my "if(info.lockcnt == 0)" ?

Is this the standard way to lock and inquire a mutex?

Thanks,
  Tobias
