Of course the list devoured the attachment. Let's try again with a
different mime-type.
#include <stdlib.h>
#include <stdio.h>
#include <xmmsclient/xmmsclient.h>
const char *fieldnames[] = {
"artist",
"album",
NULL};
static void
handle_list_dicts (xmmsv_t *val) {
xmmsv_list_iter_t *it;
xmmsv_t *dict;
unsigned int i;
const char *buf;
/* Iterate over list */
if (!xmmsv_get_list_iter (val, &it)) {
fputs ("Oh no!\n", stderr);
return;
}
for (xmmsv_list_iter_first (it);
xmmsv_list_iter_valid (it);
xmmsv_list_iter_next (it)) {
if (!xmmsv_list_iter_entry (it, &dict)) {
fputs ("Creepy!\n", stderr);
return;
}
/* print wanted fields */
for (i = 0; fieldnames[i]; i++) {
if (!xmmsv_dict_entry_get_string (dict, fieldnames[i],
&buf)) {
buf = "?????";
}
if (i > 0) {
fputc ('\t', stdout);
}
fputs (buf, stdout);
}
fputc ('\n', stdout);
}
}
int main () {
xmmsc_connection_t *conn;
xmmsc_result_t *res;
xmmsv_coll_t *univ;
xmmsv_t *fields, *val;
/* connect */
conn = xmmsc_init ("akkabakkalakkabakka");
if (!xmmsc_connect (conn, NULL)) {
fputs ("Auch!\n", stderr);
xmmsc_unref (conn);
return 1;
}
/* request stuff */
univ = xmmsv_coll_universe ();
fields = xmmsv_make_stringlist ((char **)fieldnames, -1);
res = xmmsc_coll_query_infos (conn, univ, fields, 0, 0, fields, fields);
xmmsv_unref (fields);
xmmsv_coll_unref (univ);
/* get stuff */
xmmsc_result_wait (res);

if (xmmsv_is_error (val)) {
