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

29 rusers() fills the utmpidlearr structure with data about host, and
30 returns 0 if successful. up must point to an allocated utmpidlearr
31 structure. If rusers() returns successful it will have allocated data
32 structures within the up structure, which should be freed with
33 xdr_free(3NSL) when you no longer need them:
34
35 xdr_free(xdr_utimpidlearr, up);

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

44 See the header <rpcsvc/rusers.h> for a definition of struct utmpi‐
45 dlearr.

48 rnusers() returns the number of users logged on to host (−1 if it can‐
49 not determine that number).
