.SH NAME
pthread_attr_getstackaddr, pthread_attr_setstackaddr \- get or set stackaddr attribute
.SH SYNOPSIS
.LP
.nf
cc -mt [ \fIflag\fR... ] \fIfile\fR... [ \fIlibrary\fR... ]
#include <pthread.h>

\fBint\fR \fBpthread_attr_getstackaddr\fR(\fBconst pthread_attr_t *restrict\fR \fIattr\fR,
     \fBvoid **restrict\fR \fIstackaddr\fR);

\fBint\fR \fBpthread_attr_setstackaddr\fR(\fBpthread_attr_t *\fR\fIattr\fR, \fBvoid *\fR\fIstackaddr\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The functions \fBpthread_attr_setstackaddr()\fR and \fBpthread_attr_getstackaddr()\fR, respectively, set and get the thread creation \fIstackaddr\fR attribute in the \fIattr\fR object. The \fIstackaddr\fR default is \fINULL\fR. See \fBpthread_create\fR(3C). 
.sp
.LP
The \fIstackaddr\fR attribute specifies the location of storage to be used for the created thread's stack. The size of the storage is at least  \fBPTHREAD_STACK_MIN.\fR 
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBpthread_attr_setstackaddr()\fR and \fBpthread_attr_getstackaddr()\fR return a value of  \fB0\fR. Otherwise, an error number is returned to indicate the error.
.sp
.LP
If successful, the \fBpthread_attr_getstackaddr()\fR function stores the \fIstackaddr\fR attribute value in \fIstackaddr\fR.
.SH ERRORS
