Description Owen Taylor 1999-04-12 18:38:14 UTC
Calling stat with a NULL pointer produces an oops on the
current Alpha kernel instead of correct returning
EFAULT. (as it does on Intel)

The following program demonstrates.

====
#include <sys/stat.h>
#include <string.h>
#include <stdio.h>
#include <errno.h>
#include <unistd.h>

int main ()
{
  struct stat buf;

  if (stat (NULL, &buf) != 0)
    printf("Error correctly returned: %s\n",
	    strerror (errno));
}

Comment 1 Jeff Johnson 1999-08-21 18:18:59 UTC
The behavior on 2.2.5 alpha is to generate an exception message
on the console and return EFAULT.
