This works for me. The order of the include files is important. I got it from the latest manuals Chap.3 Rev.A, May 88. #include <stdio.h> #include <rpc/rpc.h> #include <utmp.h> #include <rpcsvc/rusers.h> main(argc, argv) int argc; char **argv; { unsigned long nusers; if (argc < 2) { fprintf(stderr, "usage: %s hostname\n", argv[0]); exit(-1); } if (callrpc(argv[1], RUSERSPROG, RUSERSVERS, RUSERSPROC_NUM, xdr_void , 0, xdr_u_long, &nusers)) { fprintf(stderr, "error: callrpc\n"); exit(1); } printf("%d users on %s\n", nusers, argv[1]); exit(0); } --Sandeep Phadke
