apr-iconv docs

[Cliff Woolley <jw...@virginia.edu>]

Um, it sure would be helpful if the three functions:

API_DECLARE(apr_status_t) apr_iconv_open(const char *, const char *,
                                         apr_pool_t *, apr_iconv_t *);
API_DECLARE(apr_status_t) apr_iconv(apr_iconv_t, const char **,
                                    apr_size_t *, char **, apr_size_t *,
                                    apr_size_t *);
API_DECLARE(apr_status_t) apr_iconv_close(apr_iconv_t, apr_pool_t *);


had any documentation at all.  Would someone who knows anything about
iconv please add something?  just a description of what the args do at
least.  Then I'll re-gen the docs.

Thanks,
Cliff
