NAME
rstat − get performance data from a remote kernel
DESCRIPTION
The rstat() protocol gathers statistics from a remote kernel. (Statistics are available on items such as paging, swapping and cpu utilization.)

PROGRAMMING
#include <rpcsvc/rstat.h>
havedisk(host)
char ∗host;
rstat(host, statp)
char ∗host;
struct statstime ∗statp;
havedisk() returns 1 if host has a disk, 0 if it does not, and −1 if it cannot be determined whether host has a disk. rstat() fills in the statstime structure for host and returns 0 if it was successful. The following XDR routines are available in librpcsvc:
xdr_statstime
xdr_statsswtch
xdr_stats
