C code should be able to tell (Solaris example)
#include <inttypes.h>
#include <stdio.h>
#include <stdlib.h>
static char chararray[] = "abcdefghijklmnopqrstuvwxyz";
static char *myfunc(int i)
{
return(& chararray[i]);
}
void main(void)
{
int intx;
long longx;
char *ptrx;
(void) scanf("%d", &longx);
intx = longx;
ptrx = myfunc(longx);
(void) printf("%d\n", longx);
intx = ptrx;
ptrx = intx;
intx = (int)longx;
ptrx = (char *)intx;
intx = 2147483648L;
intx = (int) 2147483648L;
ptrx = myfunc(2147483648L);
}
Using "man lint.1" If the system is not 64-bit clean -- you will get
a lot of errors.
