[pdf-devel] what's happening with error reporting?

[Cirilo Bernardo]

What's the latest news on error reporting within the libs?

The GNU docs recommend something like
fprintf(stderr, __FILE__ ": %d: something went wrong: %s\n", __LINE__, cause);

So for example, this bit from pdf-stm-f-a85.c:

if (count != 0)
  {
    /* Error: z inside ascii85 5-tuple */
    error;
  }

can be changed to something like:

if (count != 0)
  {
    /* Error: z inside ascii85 5-tuple */
    fprintf(stderr, __FILE__ ": %d: 'z' inside ascii85 5-tuple\n", __LINE__-3);
    error;
  }

If you could indicate the position within the FILE (not within the
stream), that may be useful for debugging the read/write routines
later on because you can use a hex editor to inspect the file.
