   The function

   int pthread_mutexattr_setpshared(const pthread_mutexattr_t *attr, int pshared);

   It shall set the process-shared attribute in an initialized attributes object 'attr'.

  The process-shared attribute is set to PTHREAD_PROCESS_SHARED to permit a mutex to be
  operated upon by any thread that has access to the memory where the mutex is allocated,
  even if the mutex is allocated in memory that is shared by multiple processes.

  If the process-shared attribute is PTHREAD_PROCESS_PRIVATE, the mutex shall only be
  operated upon by threads created within the same process as the thread that initialized
  the mutex; if threads of differing processes attempt to operate on such a mutex,
  the behavior is undefined.

  The default value of the attribute is PTHREAD_PROCESS_PRIVATE.

  It MAY fail if:

  [EINVAL] - 'attr' is invalid.

  [EINVAL] - the new value pshared value is outside the range of legal values for that
             attribute.
