Manual page for RNUSERS(3R)

rnusers, rusers - return information about users on remote machines

SYNOPSIS

#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
};
