 Not sure what's happening when I try to compile this:
 //#define _KMEMUSER
 #include <stdio.h>
 #include <kvm.h>
 #include <sys/sysctl.h>
 #include <sys/param.h>
 #include <sys/fcntl.h>
 
 int main(){
 const char t[1] = {'\0'};
 kvm_t *kd = kvm_open(NULL,NULL,NULL,O_RDWR,t);
 int b;
 int *c = &b;
 struct kinfo_proc2 *a = kvm_getproc2(kd,KERN_PROC_ALL,0,9999999,c);
 printf("%d\n",a[0].p_pid);
 return 0;
 }
 
 Error:
