PTHREAD_ATTR_SETSTACKADDR(3Linux Programmer's ManuPTHREAD_ATTR_SETSTACKADDR(3)

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

SYNOPSIS
       #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.

DESCRIPTION
       These functions are obsolete: do not use them.   Use  pthread_attr_set-
       stack(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.

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

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

VERSIONS
       These functions are provided by glibc since version 2.1.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The  pthread_attr_setstackaddr()  and pthread_attr_getstackaddr() func-
       tions are thread-safe.

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

NOTES
       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 down-
       ward, 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_set-
       stack(3) and pthread_attr_getstack(3), is always a pointer to the  low-
       est  address  in  the  allocated stack area (and the stacksize argument
       specifies the range of the stack).

       size(3), pthread_create(3), pthreads(7)
