add buddy to the buddy list

[Kamanashis Roy Shuva]

Hi,

  I have wrote a purple based server that connects to the im servers
and sends ims. At first I send the im to the buddies. But the messages
did not reach in the remote end. Then I added the "purple based server
accounts" at the remote buddy list. And then I was able to get the
messages sent from this program.

  To send im to new buddy , I have first added the buddy to the buddy
list. And then sent the message. But the remote end got a request to
add buddy only for msn account. So I failed to register buddy in the
server. For more information I also initiated the buddylist system.

   So is there any way to send request for adding buddy? Or is there
any way that I can use buddy from database ?

   Here are some important parts of my code,


static void add_newone(PurpleAccount *account, const char *username,
const char *group, const char *alias) {
	PurpleGroup *grp;
	PurpleBuddy *buddy;
	
	/* see if the buddy is already there */
	if(purple_find_buddy( account, username)) {
		return;
	}
	
	grp = purple_find_group(group);
	if (!grp) {
		/* creating a new group */
		grp = purple_group_new(group);
		purple_blist_add_group(grp, NULL);
	}
	buddy = purple_buddy_new(account, username, alias);
	purple_blist_add_buddy(buddy, NULL, grp, NULL);
	purple_account_add_buddy(account, buddy);
	ECHOC("added buddy %s in account
%s\n",username,purple_account_get_username(account));
}

static void nullclient_permit_anyone(PurpleAccount *account, const
char *username, const char *group, const char *alias) {
	ECHOC("request accepted for buddy %s in account
%s\n",username,purple_account_get_username(account));
	add_newone(account, username, group, alias);
}

	iter = purple_accounts_get_all_active();
	for (; iter; iter = iter->next) {
		acc = iter->data;
