[Flex-help] Multiple file processing

[Gautier DI F. <gau...@gm...>]

Hi all,

I want to process many files, so I add this at the end of my xml.l:
int ParseXml(char *s)
{
    int err = 0;
    XMLin = fopen(s, "r");

    if (!XMLin) {
        puts("Error on XML file opening\n");
    } else {
        XML_switch_to_buffer( XML_create_buffer( XMLin, YY_BUF_SIZE ) );
        err = XMLparse();
        XML_delete_buffer( YY_CURRENT_BUFFER );
        fclose(XMLin);
    }

    return err;
}

On the first execution it works (it returns 0), but on the second call it
fails (it returns 1).
According to http://flex.sourceforge.net/manual/Multiple-Input-Buffers.htmlit
should works!

What do I do wrong?

For your help,
Thanks by advance.
