This is My Code:
1 #include<sys/param.h>
2 #include<sys/jail.h>
3 #include<arpa/inet.h>
4 #include<stdio.h>
5 #include<errno.h>
6=20
7 int main()
8 {
9 int jid;
10 struct jail j;
11 struct in_addr ip4;
12 const char *cp=3D"192.168.1.10";
13=20
14 j.version=3DJAIL_API_VERSION;
15 j.path=3D"/home/mk/jail";
16 j.hostname=3D"testJail";
17 j.jailname=3D"test";
18 j.ip4s=3Dinet_addr(cp);
19 j.ip6s=3D0;
20=20
21 if(1!=3Dinet_aton(cp,&ip4))
22 printf("the address is invalid\r\n");
23=20
24 j.ip4=3D&ip4;
25 j.ip6=3DNULL;
26=20
27 jid=3Djail(&j);
28=20
29 switch(errno){
30 case EPERM:
31 printf("eperm\r\n");
32 break;
33 case EFAULT:
34 printf("efault\r\n");
35 break;
36 case EINVAL:
37 printf("einval\r\n");
38 break;
39=20
40 case EAGAIN:
41 printf("eagain\r\n");
42 }
47 return 0;
48 }
The problem is it will print `einval`,it means `The version number of =
the argument is not correct.`
How to solve it?
