PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       pthread_attr_getstacksize, pthread_attr_setstacksize — get and set the
13       stacksize attribute
14

SYNOPSIS

16       #include <pthread.h>
17
18       int pthread_attr_getstacksize(const pthread_attr_t *restrict attr,
19           size_t *restrict stacksize);
20       int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize);
21

DESCRIPTION

23       The  pthread_attr_getstacksize()  and pthread_attr_setstacksize() func‐
24       tions, respectively, shall get and set the  thread  creation  stacksize
25       attribute in the attr object.
26
27       The  stacksize attribute shall define the minimum stack size (in bytes)
28       allocated for the created threads stack.
29
30       The behavior is undefined if the value specified by the  attr  argument
31       to  pthread_attr_getstacksize() or pthread_attr_setstacksize() does not
32       refer to an initialized thread attributes object.
33

RETURN VALUE

35       Upon    successful    completion,    pthread_attr_getstacksize()    and
36       pthread_attr_setstacksize()  shall  return  a value of 0; otherwise, an
37       error number shall be returned to indicate the error.
38
39       The pthread_attr_getstacksize() function stores the stacksize attribute
40       value in stacksize if successful.
41

ERRORS

43       The pthread_attr_setstacksize() function shall fail if:
44
45       EINVAL The  value  of  stacksize  is  less  than {PTHREAD_STACK_MIN} or
46              exceeds a system-imposed limit.
47
48       These functions shall not return an error code of [EINTR].

EXAMPLES

53       None.
54

APPLICATION USAGE

56       None.
57

RATIONALE

59       If an implementation detects that the value specified by the attr argu‐
60       ment to pthread_attr_getstacksize() or pthread_attr_setstacksize() does
61       not refer to an initialized thread attributes object, it is recommended
62       that the function should fail and report an [EINVAL] error.
63

FUTURE DIRECTIONS

65       None.
