PTHREAD_ATTR_SETSTACKADDR(3)				     Linux Programmer's Manual				      PTHREAD_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_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.

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.

       For an explanation of the terms used in this section, see attributes(7).

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 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 allo-
       cated  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).
