Use FUNCTION definition et al. 20 Fixed include order. Make everything static. Ifdef around 21 some headers. 22 Modified at NRL for OPIE 2.1. Substitute @@KEY_FILE@@. Re-write in 23 C. 24 Modified at NRL for OPIE 2.01. Remove hard-coded paths for grep and 25 awk and let PATH take care of it. Substitute for Makefile 26 variables $(EXISTS) and $(KEY_FILE). Only compute $WHO if 27 there's a key file. Got rid of grep since awk can do the job 28 itself. 29 Modified at NRL for OPIE 2.0. 30 Written at Bellcore for the S/Key Version 1 software distribution 31 (keyinfo) 32 33$FreeBSD: head/contrib/opie/opieinfo.c 78644 2001-06-23 04:48:59Z ache $ 34 35*/ 36 37#include "opie_cfg.h" 38#include <stdio.h> 39#if HAVE_UNISTD_H 40#include <unistd.h> 41#endif /* HAVE_UNISTD_H */ 42#include "opie.h" 43 44/* extern char *optarg; */ 45extern int errno, optind; 46 47static char *getusername FUNCTION_NOARGS 48{ 49 char *login; 50 51 login = getlogin(); 52 if (login == NULL) { 53 fprintf(stderr, "Cannot find login name\n"); 54 exit(1); 55 } 56 return login; 57} 58 59int main FUNCTION((argc, argv), int argc AND char *argv[]) 60{ 61 char *username; 62 struct opie opie; 63 int i; 64 65 while ((i = getopt(argc, argv, "hv")) != EOF) { 66 switch (i) { 67 case 'v': 68 opieversion(); 69 case 'h': 70 default: 71 fprintf(stderr, "usage: %s [-h] [-v] [user_name]\n", argv[0]); 72 exit(0); 73 } 74 } 75 76 if (optind < argc) { 77 if (getuid() != 0) { 78 fprintf(stderr, "Only superuser may get another user's keys\n"); 79 exit(1); 80 } 81 username = argv[optind]; 82 } else 83 username = getusername(); 84 85 if ((i = opielookup(&opie, username)) && (i != 2)) { 86 if (i < 0) 87 fprintf(stderr, "Error opening database!
