RPC Library Functionsrusers(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
