PTHREAD_ATTR_GETSTACKSIZE(3P)                       POSIX Programmer's Manual                      PTHREAD_ATTR_GETSTACKSIZE(3P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult 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.

RETURN VALUE
       Upon successful completion, pthread_attr_getstacksize() and pthread_attr_setstacksize() shall return a value of 0; other-
       wise, 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].
