Re: emacs & MAXPATHLEN

[Alfred M\. Szmidt]

   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;
   }
