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


NAME
       pthread_attr_getstacksize, pthread_attr_setstacksize — get and set the stacksize attribute


SYNOPSIS
       #include <pthread.h>

       int pthread_attr_getstacksize(const pthread_attr_t *restrict attr,
           size_t *restrict stacksize);
       int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize);


DESCRIPTION
       The  pthread_attr_getstacksize()  and  pthread_attr_setstacksize() functions, respectively, shall get and
       set the thread creation stacksize attribute in the attr object.

       The stacksize attribute shall define the minimum stack size (in bytes) allocated for the created  threads
       stack.

       The  behavior  is undefined if the value specified by the attr argument to pthread_attr_getstacksize() or
       pthread_attr_setstacksize() does not refer to an initialized thread attributes object.


RETURN VALUE
       Upon successful completion, pthread_attr_getstacksize() and pthread_attr_setstacksize()  shall  return  a
       value of 0; otherwise, an error number shall be returned to indicate the error.

       The pthread_attr_getstacksize() function stores the stacksize attribute value in stacksize if successful.


ERRORS
       The pthread_attr_setstacksize() function shall fail if:

       EINVAL The value of stacksize is less than {PTHREAD_STACK_MIN} or exceeds a system-imposed limit.

       These functions shall not return an error code of [EINTR].

       The following sections are informative.


EXAMPLES
       None.


APPLICATION USAGE
       None.


RATIONALE
       If an implementation detects that the value specified by the attr argument to pthread_attr_getstacksize()
       or pthread_attr_setstacksize() does  not  refer  to  an  initialized  thread  attributes  object,  it  is
       recommended that the function should fail and report an [EINVAL] error.


FUTURE DIRECTIONS
       None.
