pthread_attr_setstackaddr(3Library Functions Manuapthread_attr_setstackaddr(3)
NAME
pthread_attr_setstackaddr, pthread_attr_getstackaddr - set/get stack
address 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 attri-
bute 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 buf-
fer 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).

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 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).
