rusers(3RPC)						       RPC Library Functions						      rusers(3RPC)

NAME

       rusers, rnusers - return information about users on remote machines

SYNOPSIS

       cc [ flag ... ] file ... -lrpcsvc [ library ... ]
       #include <rpc/rpc.h>
       #include <rpcsvc/rusers.h>

       enum clnt_stat rusers(char *host, struct utmpidlearr *up);

       int rnusers(char *host);

PROTOCOL

       /usr/include/rpcsvc/rusers.x

DESCRIPTION

       These  routines	require  that  the rpc.rusersd(1M) daemon be configured and available on the remote system indicated by host. The rusers()
       protocol is used to retrieve information about users logged in on the remote system.

       rusers() fills the utmpidlearr structure with data about host, and returns 0 if successful. up  must  point  to	an  allocated  utmpidlearr
       structure.  If  rusers()  returns  successful  it  will	have allocated data structures within the up structure, which should be freed with
       xdr_free(3NSL) when you no longer need them:

       xdr_free(xdr_utimpidlearr, up);

       On error, the returned value can be interpreted as an  enum clnt_stat and can be displayed with clnt_perror(3NSL) or  clnt_sperrno(3NSL).

       See the header  <rpcsvc/rusers.h> for a definition of struct  utmpidlearr.

       rnusers() returns the number of users logged on to host (-1 if it cannot determine that number).

       The following  XDR routines are available in librpcsvc:

       xdr_utmpidlearr
