Any one up for OSX work.

I’ll try when I get home (in a few hours).

I did some testing, and yes, if a variable isn’t assigned a value, it returns 0.

That is - unless there hasn’t been declared/assigned a value to some other variable. Then it returns 4096.

$ cat und.c
#include <stdio.h>

void main(void)
{
	int i=4;
	int j;
	int *k=&i;
	int *l;
	printf("%d\n%d\n",i,j);
	printf("%d\n%d\n",k,l);
}

gives

$ ./und
