       These functions are obsolete: donotusethem.  Use pthread_attr_setstack(3) and pthread_attr_getstack(3)
       instead.

       The pthread_attr_setstackaddr() function sets the stack address attribute of the thread attributes object
       referred to by attr to the value specified in stackaddr.  This attribute specifies the  location  of  the
       stack that should be used by a thread that is created using the thread attributes object attr.

       stackaddr  should point to a buffer of at least PTHREAD_STACK_MIN bytes that was allocated by the caller.
       The pages of the allocated buffer should be both readable and writable.

       The pthread_attr_getstackaddr() function returns the stack address attribute  of  the  thread  attributes
       object referred to by attr in the buffer pointed to by stackaddr.

       No errors are defined (but applications should nevertheless handle a possible error return).

       attributes object

Donotusethesefunctions!  They cannot be portably used, since they provide no way of specifying the
       direction of growth or the range of the stack.  For example, on architectures with  a  stack  that  grows
       downward,  stackaddr  specifies  the  next  address past the highest address of the allocated stack area.
       However, on architectures with a stack that grows upward, stackaddr specifies the lowest address  in  the
       allocated   stack   area.    By   contrast,   the   stackaddr   used   by   pthread_attr_setstack(3)  and
       pthread_attr_getstack(3), is always a pointer to the lowest address in the allocated stack area (and  the
       stacksize argument specifies the range of the stack).

       On success, these functions return 0; on error, they return a nonzero error number.
