◆ imap_sync_message_for_copy()

int imap_sync_message_for_copy ( struct Mailbox * m,

enum QuadOption * err_continue )

Update server to reflect the flags of a single message.

Parameters
[in]mMailbox
[in]eEmail
[in]cmdBuffer for the command string
[out]err_continueDid the user force a continue?
Return values
0Success
-1Failure

Update the IMAP server to reflect the flags for a single message before performing a "UID COPY".

Note
This does not sync the "deleted" flag state, because it is not desirable to propagate that flag into the copy.

◆ imap_cmd_finish()

void imap_cmd_finish ( struct ImapAccountData * adata)

Attempt to perform cleanup.

Parameters
adataImap Account data

If a reopen is allowed, it attempts to perform cleanup (eg fetch new mail if detected, do expunge). Called automatically by imap_cmd_step(), but may be called at any time.

mdata->check_status is set and will be used later by imap_check_mailbox().

Fill the message header according to the server flags.

Parameters
[in]mImap Selected Mailbox
[in]eEmail
[in]sCommand string
[out]server_changesSet to true if the flags have changed
Return values
ptrThe end of flags string

Parameters

Return values

Note
the first character in mailbox matching any of the characters in $imap_delim_chars is used as a delimiter.

This is necessary because the rest of neomutt assumes a hierarchy delimiter of '/', which is not necessarily true in IMAP. Additionally, the filesystem converts multiple hierarchy delimiters into a single one, ie "///" is equal to "/". IMAP servers are not required to do this. Moreover, IMAP servers may dislike the path ending with the delimiter.
