PTHREAD_ATTR_SETSTACKADDR(3)nux Programmer's ManualREAD_ATTR_SETSTACKADDR(3)
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 return).
These functions are provided by glibc since version 2.1.
For an explanation of the terms used in this section, see
attributes(7).

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).
