mail::ACCOUNT::copyMessagesTo — Copy messages to another folder
#include <libmail/sync.H> mail::ACCOUNT *mail; mail::folder *folder;
bool ok=mail->copyMessagesTo(const std::vector<size_t> &msgList, mail::folder *copyTo);
msgList specifies a list of messages. Messages are numbered starting with message #0 and up to one less than mail::ACCOUNT::getFolderIndexSize(3x) (when mail::account::getFolderIndexSize returns 6, the messages are numbered 0 through 5). Only the messages that appear in msgList are processed by this request. When a message is removed from the folder, by mail::ACCOUNT::updateFolderIndexInfo(3x), the following messages are renumbered accordingly.
Most mail servers allow multiple applications to open the same folder. Therefore, changes to the folder's contents can occur at any time. Before making this request, the application should use mail::ACCOUNT::checkNewMail(3x) to verify that no unexpected changes have been made to the folder's contents.
mail::ACCOUNT::copyMessagesTo copies messages in the currently-open folder to another folder. copyTo is a pointer to a mail::folder object, representing the folder where messages are copied to. If account is an IMAP account and copyTo is another folder in the same account, then the messages are quickly copied by the IMAP server. Otherwise each message is individually downloaded and copied to the copyTo folder.
This method returns true if it succeeds, or false if it fails. If the method fails, use mail::ACCOUNT::getErrmsg() to read a brief description of the error.
