This is my part c code:
11 int main() 12 { 13 in_addr_t addr_t=inet_addr("192.168.2.1"); 14 15 struct in_addr in_addr=inet_makeaddr(addr_t,AF_INET); 16 17 18 struct jail j={ 19 .version=JAIL_API_VERSION, 20 .path="./jail_test", 21 .hostname="myjail", 22 .ip4s=addr_t, 23 .ip6s=0, 24 .ip4=&in_addr, 25 .ip6=NULL 26 }; 27 28 errno=0; 29 int rs=jail(&j); 30 if(0==rs){ 31 printf("create jail ok!!!\r\n"); 32 return 0; 33 } 34 35 switch(errno){ 36 case EPERM: 37 printf("eperm\r\n"); 38 break; 39 case EFAULT: 40 printf("efault\r\n"); 41 break; 42 case EINVAL: 43 printf("einval\r\n"); 44 break; 45 case EAGAIN: 46 printf("eagain\r\n"); 47 break; 48 default: 49 printf("---------------\r\n"); 50 break; 51 } 52 return 0; 53 } Unfortunately,the errno return EINVAL,it means “The version number of the argument is not correct.”,why? _______________________________________________ freebsd-jail@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-jail To unsubscribe, send any mail to "freebsd-jail-unsubscr...@freebsd.org"
