Hello,
I am writing a program called jailstat, which goes through the proc
structure, checks if p_prison is true, if it is, prints out
p_prison->pr_host.
I have it working so it says, "jailed process", and prints out it's UID.
But, when I try to make it print the hostname, this is what happens.
Here's a snippet of code:
if ((kinfo = malloc(nentries * sizeof(*kinfo))) == NULL)
err(1, NULL);
for (i = nentries; --i >= 0; ++proc_list) {
(&kinfo[i])->ki_p = proc_list;
if (KI_PROC(&kinfo[i])->p_prison)
{
printf("Jailed Process\n");
printf("%s\n",
KI_PROC(&kinfo[i])->p_prison->pr_host);
}
}
KI_PROC is just a macro that is
#define KI_PROC(ki) (&(ki)->ki_p->kp_proc)
[teqnix](~/work/c/getprocs)%gcc -g -lkvm getprocs.c -o getprocs
getprocs.c: In function `main':
getprocs.c:87: dereferencing pointer to incomplete type
If anyone could give a little help. Thanks a lot. :-)
