   pthread_*() functions return nonzero value to indicate the error,
   you can check pthread_mutex_lock() return value if a lock by mutex
   is asquired.
   Note that with 2CPU machine, maybe, EDEADLK on the mutex
   by the calling thread.
 
  (and maybe, you can also validate the `c' pointer :)

   linux is irrelevant to threads.
   hpux is irrelevant to threads.
   threads is irrelevant to C++.
   C++ is irrelevant to programming languages.
