PTHREAD_ATTR_SETSTACKADDR(3) Linux Programmer's Manual PTHREAD_ATTR_SETSTACKADDR(3)
pthread_attr_setstackaddr, pthread_attr_getstackaddr - set/get stack address attribute in
thread attributes object
int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
int pthread_attr_getstackaddr(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
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
These functions are provided by glibc since version 2.1.
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 architec-
tures with a stack that grows downwards, stackaddr specifies the next address past the
highest address of the allocated stack area. However, on architectures with a stack that
grows upwards, 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).
