Re: system()

[jim @ Tadpole . COM (Jim Thompson)]

I don't know if I'd trust anything that tromps through what could be a
NULL pointer.  In this case, 'dst' could be NULL (if malloc fails), and
the program would print the warning, then dump core (unless run on a
little-endian machine, say, a VAX.)

/* strndup - make copy of string */
static char *strndup(str, len)
char   *str;
int     len;
{
    char   *dst;

    if ((dst = malloc(len + 1)) == 0)
      fprintf(stderr, "%s: out of memory\n", myname);
    dst[len] = 0;
    return (strncpy(dst, str, len));
}
