.SH NAME
pthread_attr_getstacksize, pthread_attr_setstacksize \- get and set
the stacksize attribute
.SH SYNOPSIS
.LP
\fB#include <pthread.h>
.br
.sp
int pthread_attr_getstacksize(const pthread_attr_t *restrict\fP \fIattr\fP\fB,
.br
\ \ \ \ \ \  size_t *restrict\fP \fIstacksize\fP\fB);

.SH DESCRIPTION
.LP
The \fIpthread_attr_getstacksize\fP() and \fIpthread_attr_setstacksize\fP()
functions, respectively, shall get and set the
thread creation \fIstacksize\fP attribute in the \fIattr\fP object.
.LP
The \fIstacksize\fP attribute shall define the minimum stack size
(in bytes) allocated for the created threads stack.
.SH RETURN VALUE
.LP
Upon successful completion, \fIpthread_attr_getstacksize\fP() and
\fIpthread_attr_setstacksize\fP() shall return a value of 0;
otherwise, an error number shall be returned to indicate the error.
.LP
The \fIpthread_attr_getstacksize\fP() function stores the \fIstacksize\fP
attribute value in \fIstacksize\fP if
successful.
.SH ERRORS
.LP
The \fIpthread_attr_setstacksize\fP() function shall fail if:
.TP 7
.B EINVAL
The value of \fIstacksize\fP is less than {PTHREAD_STACK_MIN} or exceeds
a system-imposed limit.
.sp
.LP
These functions shall not return an error code of [EINTR].
