NAME

rstat, havedisk − get performance data from remote kernel

SYNOPSIS

#include <time.h>
#include <rpcsvc/rstat.h>
havedisk(host)
char *host;
rstat(host, statp)
char *host;
struct statstime *statp;

DESCRIPTION

The havedisk function returns 1 if host has a disk, 0 if it does not, and −1 if this cannot be determined.  The host string is either the official name of the host or an alias for it.  See hosts(4) for more information regarding host names.
 
The rstat function fills in the statstime structure for host, and returns 0 if it was successful. The relevant structures are:

 struct stats {                /* RSTATVERS_ORIG */
     int cp_time[CPUSTATES];  /* the time spent in each CPU
                                 state */
     int dk_xfer[DK_NDRIVE];  /* total number of disk
                                 transfers on each of the
                                 disk interfaces */
     unsigned v_pgpgin;       /* total VM pages paged in */
     unsigned v_pgpgout;      /* total VM pages paged out */
