and leaks memory. If the path is 400, you do 3 mallocs, but the
first two are never freed.
That is just a small matter of moving the free outside the if. :-)
int buf_size = 100;
while (1)
{
buf = (char *) xmalloc (buf_size);
if (getcwd (buf, buf_size) == buf)
break;
free (buf);
if (errno != ERANGE)
fatal ("`getcwd' failed: %s\n", strerror (errno));
size *= 2;
}
