hai all
i have written a kernel module.code is working fine.i am getting 2 warnings
they are

/home/indu/pgs/kernpr/client/cc.c: In function ‘sockfn’:
/home/indu/pgs/kernpr/client/cc.c:31: warning: ‘return’ with a value, in function returning void
/home/indu/pgs/kernpr/client/cc.c:37: warning: implicit declaration of function ‘in_aton’
Building modules, stage 2


these are the lines
1. sin.sin_family = AF_INET;
sin.sin_addr.s_addr = (in_aton("ipaddress"));
2.
error = sock_create(AF_INET,SOCK_STREAM,IPPROTO_TCP,&sock) ;
if (error<0)
{
printk("Error\n");
return 0;
}
can anyone tell me where i went wrong?
