       pthread_attr_setstackaddr,  pthread_attr_getstackaddr - set/get stack address attribute in
       thread attributes object


       #include <pthread.h>

       int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
       int pthread_attr_getstackaddr(const pthread_attr_t *attr, void **stackaddr);

       Compile and link with -pthread.


       These  functions  are  obsolete:  do  not  use  them.   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.


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


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


       These functions are provided by glibc since version 2.1.

       POSIX.1-2001 specifies these functions but marks them as obsolete.   POSIX.1-2008  removes
       the specification of these functions.


       Do  not  use  these functions!  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).
