.SH DESCRIPTION
.sp
.LP
These routines require that the \fBrpc.rstatd\fR(1M) daemon be configured and available on the remote system indicated by \fIhost\fR. The \fBrstat()\fR protocol is used to gather statistics from remote kernel.  Statistics will be available on items such as paging, swapping, and cpu utilization.
.sp
.LP
\fBrstat()\fR fills in the \fBstatstime\fR structure \fIstatp\fR for \fIhost\fR.  \fIstatp\fR must point to an allocated \fBstatstime\fR structure. \fBrstat()\fR returns \fBRPC_SUCCESS\fR if it was successful; otherwise a \fBenum clnt_stat\fR is returned which can be displayed using \fBclnt_perrno\fR(3NSL).
.sp
.LP
\fBhavedisk()\fR returns \fB1\fR if \fIhost\fR has disk, \fB0\fR if it does not, and \fB\(mi1\fR if this cannot be determined.
