  32 .sp
  33 .LP
  34 The functions \fBpthread_attr_setstackaddr()\fR and
  35 \fBpthread_attr_getstackaddr()\fR, respectively, set and get the thread
  36 creation \fIstackaddr\fR attribute in the \fIattr\fR object. The
  37 \fIstackaddr\fR default is \fINULL\fR. See \fBpthread_create\fR(3C).
  38 .sp
  39 .LP
  40 The \fIstackaddr\fR attribute specifies the location of storage to be used for
  41 the created thread's stack. The size of the storage is at least
  42 \fBPTHREAD_STACK_MIN.\fR
  43 .SH RETURN VALUES
  44 .sp
  45 .LP
  46 Upon successful completion, \fBpthread_attr_setstackaddr()\fR and
  47 \fBpthread_attr_getstackaddr()\fR return a value of  \fB0\fR. Otherwise, an
  48 error number is returned to indicate the error.
  49 .sp
  50 .LP
  51 If successful, the \fBpthread_attr_getstackaddr()\fR function stores the
  52 \fIstackaddr\fR attribute value in \fIstackaddr\fR.
