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
#include <pthread.h>
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 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.
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).
