I don't see how _notmuch_message_list_append works. It says "node can of course point to an arbitrarily long list of nodes", but the code is: void _notmuch_message_list_append (notmuch_message_list_t *list, notmuch_message_node_t *node) { *(list->tail) = node; list->tail = &node->next; } Should not be something like: void _notmuch_message_list_append (notmuch_message_list_t *list, notmuch_message_node_t *node) { notmuch_message_node_t *next_node; *(list->tail) = node; for (next_node = node->next; next_node->next != NULL; next_node = next_node->next); list->tail = &next_node->next; } Do I miss something? Or the function is just designed to work on a single node not a list of them? -- Rubén Pollán | jabber:meskio@jabber.org -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- No vamos a reivindicar nada, no vamos a pedir nada.
