Ahh I got it working now. Thanks so much! I really appreciate it.
Here's my working code now for anyone who's interested...
gboolean re_request_buddy(gpointer data)
{
PurpleBuddy *buddy = data;
if (buddy!=NULL)
{
printf("Re-requesting authorization for %s (%s)...\n",
purple_buddy_get_name(buddy),
purple_account_get_protocol_id(purple_buddy_get_account(buddy)));
PurplePluginProtocolInfo *prpl_info =
PURPLE_PLUGIN_PROTOCOL_INFO(purple_account_get_connection(purple_buddy_get_account(buddy))->prpl);
if (prpl_info && prpl_info->blist_node_menu)
{
GList *menu = prpl_info->blist_node_menu((PurpleBlistNode *)buddy);
while (menu)
{
PurpleMenuAction *menu_action = menu->data;
if (g_str_equal(menu_action->label, "Re-request Authorization"))
{
printf("Found re-request menu option...\n");
gpointer data;
void (*callback)(gpointer, gpointer);
callback = (void *)menu_action->callback;
data = menu_action->data;
if (callback)
{
callback(((PurpleBlistNode *)buddy), data);
printf("Re-requested authorization\n");
}
}
/* Destroy the data in the linked list */
purple_menu_action_free(menu_action);
/* Remove this node from the list */
menu = g_list_delete_link(menu, menu);
}
}
else
{
printf("Re-request authorization failed because the buddy's menu
does not exist for %s (%s)\n", purple_buddy_get_name(buddy),
purple_account_get_protocol_id(purple_buddy_get_account(buddy)));
}
}
else
{
printf("Re-request authorization failed because buddy does not exist
\n");
}
}
