pthread_at...etstackaddr(3) Library Functions Manualpthread_at...etstackaddr(3)
NAME
pthread_attr_setstackaddr, pthread_attr_getstackaddr - set/get stack ad-
dress attribute in thread attributes object
LIBRARY
POSIX threads library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h>
[[deprecated]]
int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
[[deprecated]]
int pthread_attr_getstackaddr(const pthread_attr_t *restrict attr,
void **restrict stackaddr);
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 at-
tribute 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 at-
tribute 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).
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

HISTORY
glibc 2.1. Marked obsolete in POSIX.1-2001. Removed in POSIX.1-2008.
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 al-
located 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).
