Re: [Evolution-hackers] Getting all mail

[Filipe Nepomuceno <filinep gmail com>]

Thanks Milan.

The problem I'm having now is when I ask for the folderinfo it returns
a null pointer at the point indicated below.
Evolution is set-up with a gmail pop account. When I tried it with the
IMAP settings it worked and I managed to get the CamelFolders.

The other thing I don't understand is the threading thing. Could
someone please explain that.

One more question, I cant seem to compile the devel-guide, is there an
online version of it? I've just been grepping everything and wanted to
know if there is some kind of API out there that makes it easier.


//mail grabbing entry point
gboolean pimp_mail_init(void)
{
	EAccountList* accounts;
	EIterator* accIter;
	
	//get accounts
	if(!(accounts = mail_config_get_accounts()))
		return FALSE;
	
	//foreach account
	accIter = e_list_get_iterator((EList *) accounts);
	while(e_iterator_is_valid(accIter))
	{
		EAccount *acc = (EAccount *) e_iterator_get(accIter);
		
		//get store
		mail_get_store(e_account_get_string(acc, E_ACCOUNT_SOURCE_URL),
NULL, pimp_mail_get_store, NULL);
				
		e_iterator_next(accIter);
	}
	
	return TRUE;
}

static void pimp_mail_get_store(char *uri, CamelStore *store, void *user_data)
{	
	if(store == NULL)
		return;
		
	//get folderinfo
	mail_get_folderinfo(store, NULL, pimp_mail_get_folderinfo, NULL);
}

static gboolean pimp_mail_get_folderinfo(CamelStore *store,
CamelFolderInfo *info, void *data)
{
	if(info == NULL)
<----------------------------------------------------------------------Null
pointer
		return FALSE;
	
	//function call to get other folderinfo's
	pimp_mail_get_folderinfo_recursive(info);
	return TRUE;
}

static void pimp_mail_get_folderinfo_recursive(CamelFolderInfo *info)
{
	//does this recursion work???? is it the right way to do it?
	if(info->child != NULL)
		pimp_mail_get_folderinfo_recursive(info->child);
	
	if(info->next != NULL)
		pimp_mail_get_folderinfo_recursive(info->next);
	
	mail_get_folder(info->uri, 0, pimp_mail_get_folder, NULL,
mail_msg_unordered_push/*dunno what this does*/);
}

static void pimp_mail_get_folder(char *uri, CamelFolder *folder, void *data)
{
	/*
	if(folder != NULL)
		camel calls in here
	*/
		
}
