Description

   This routine copies the object name from the condition variable
   object specified by the cond argument to the buffer at the
   location specified by the name argument. Before calling this
   routine, your program must allocate the buffer indicated by name.

   The object name is a C language string and provides an identifier
   that is meaningful to a person debugging a multithreaded
   application. The maximum number of characters in the object name
   is 31.

   If the specified condition variable object has not been
   previously set with an object name, this routine copies a C
   language null string into the buffer at location name.
