rstat - get performance data from remote kernel
The rstat() protocol is used to gather statistics from remote kernel.
Statistics are available on items such as paging, swapping and cpu uti-
struct statstime *statp;
havedisk() returns 1 if host has a disk, 0 if it does not, and -1 if
this cannot be determined. rstat() fills in the statstime structure
for host, and returns 0 if it was successful.
The following XDR routines are available in librpcsvc:
perfmeter(1), rup(1C), rstatd(8C)
