RNUSERS(3R)         RISC/os Reference Manual          RNUSERS(3R)



NAME
     rnusers, rusers - return information about users on remote
     machines

SYNOPSIS
     For -systype sysv and -systype bsd43:

     #include <rpcsvc/rusers.h>

     rnusers(host)
          char *host
     rusers(host, up)
          char *host
          struct utmpidlearr *up;

DESCRIPTION
     rnusers returns the number of users logged on to host (-1 if
     it cannot determine that number).  rusers fills the
     utmpidlearr structure with data about host, and returns 0 if
     successful.  The relevant structures are:

     struct utmparr {              /* RUSERSVERS_ORIG */
          struct utmp **uta_arr;
          int uta_cnt
     };

     struct utmpidle {
          struct utmp ui_utmp;
          unsigned ui_idle;
     };
     struct utmpidlearr {          /* RUSERSVERS_IDLE */
          struct utmpidle **uia_arr;
          int uia_cnt
     };

          int xdr_utmpidleptr(xdrs, up);
               XDR *xdrs;

     procs:

     RUSERSPROC_NUM No arguments, returns number of users as an
                    unsigned long.

     RUSERSPROC_NAMES
                    No arguments, returns utmparr or utmpidlearr,
                    depending on version number.

     RUSERSPROC_ALLNAMES
                    No arguments, returns utmparr or utmpidlearr,
                    depending on version number.  Returns listing
                    even for utmp entries satisfying nonuser() in
                    utmp.h.
