Description

   This routine sets the stacksize attribute in the thread
   attributes object specified by the attr argument. Use this
   routine to adjust the size of the writable area of the stack
   for a new thread.

   The size of a thread's stack is fixed at the time of thread
   creation. On OpenVMS systems, only the initial thread can
   dynamically extend its stack. On Tru64 UNIX systems, very large
   stacks can be created, but only a few pages are committed.

   Many compilers do not check for stack overflow. Ensure that the
   new thread's stack is sufficient for the resources required by
   routines that are called from the thread.
