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 $FreeBSD$ 34 35 */ 36 37 #include "opie_cfg.h" 38 #include <sys/param.h> 39 #include <errno.h> 40 #include <stdio.h> 41 #include <stdlib.h> 42 #include <string.h> 43 #if HAVE_UNISTD_H 44 #include <unistd.h> 45 #endif /* HAVE_UNISTD_H */ 46 #include "opie.h" 47 48 /* extern char *optarg; */ 49 /* extern int errno, optind; */ 50 51 static char *getusername FUNCTION_NOARGS 52 { 53 char *login; 54 55 login = getlogin(); 56 if (login == NULL) { 57 fprintf(stderr, "Cannot find login name\n"); 58 exit(1); 59 } 60 return login; 61 } 62 63 int main FUNCTION((argc, argv), int argc AND char *argv[]) 64 { 65 char *username; 66 struct opie opie; 67 int i; 68 69 while ((i = getopt(argc, argv, "hv")) != EOF) { 70 switch (i) { 71 case 'v': 72 opieversion(); 73 case 'h': 74 default: 75 fprintf(stderr, "usage: %s [-h] [-v] [user_name]\n", argv[0]); 76 exit(0); 77 } 78 } 79 80 if (optind < argc) { 81 if (getuid() != 0) { 82 fprintf(stderr, "Only superuser may get another user's keys\n"); 83 exit(1); 84 } 85 username = argv[optind]; 86 } else 87 username = getusername(); 88 89 if (strlen(username) >= MAXLOGNAME) { 90 fprintf(stderr, "Username too long.\n"); 91 exit(1); 92 } 93 94 if ((i = opielookup(&opie, username)) && (i != 2)) { 95 if (i < 0) 96 fprintf(stderr, "Error opening database!
