NAME

6       pthread_attr_setstackaddr,  pthread_attr_getstackaddr  -  set/get stack
7       address attribute in thread attributes object
8

SYNOPSIS

10       #include <pthread.h>
11
12       int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
13       int pthread_attr_getstackaddr(const pthread_attr_t *restrict attr,
14                                     void **restrict stackaddr);
15
16       Compile and link with -pthread.

DESCRIPTION

19       These functions are obsolete: do not use them.   Use  pthread_attr_set‐
20       stack(3) and pthread_attr_getstack(3) instead.
21
22       The  pthread_attr_setstackaddr() function sets the stack address attri‐
23       bute of the thread attributes object referred to by attr to  the  value
24       specified  in  stackaddr.  This attribute specifies the location of the
25       stack that should be used by a thread that is created using the  thread
26       attributes object attr.
27
28       stackaddr  should point to a buffer of at least PTHREAD_STACK_MIN bytes
29       that was allocated by the caller.  The pages of  the  allocated  buffer
30       should be both readable and writable.
31
32       The  pthread_attr_getstackaddr() function returns the stack address at‐
33       tribute of the thread attributes object referred to by attr in the buf‐
34       fer pointed to by stackaddr.
35

RETURN VALUE

37       On  success,  these functions return 0; on error, they return a nonzero
38       error number.
39

ERRORS

41       No errors are defined (but applications should  nevertheless  handle  a
42       possible error return).
43

VERSIONS

45       These functions are provided by glibc since version 2.1.

CONFORMING TO

59       POSIX.1-2001  specifies  these  functions  but  marks them as obsolete.
60       POSIX.1-2008 removes the specification of these functions.
61

NOTES

63       Do not use these functions!  They cannot be portably used,  since  they
64       provide  no  way  of specifying the direction of growth or the range of
65       the stack.  For example, on architectures with a stack that grows down‐
66       ward,  stackaddr specifies the next address past the highest address of
67       the allocated stack area.  However, on architectures with a stack  that
68       grows  upward,  stackaddr specifies the lowest address in the allocated
69       stack area.  By  contrast,  the  stackaddr  used  by  pthread_attr_set‐
70       stack(3)  and pthread_attr_getstack(3), is always a pointer to the low‐
71       est address in the allocated stack area  (and  the  stacksize  argument
72       specifies the range of the stack).
