This is also something I'm looking at doing - I want to log both the UID
and the GUID to the log. I also want to make sure that APPEND gets
logged as well, and DELETE.
You should find that you can use the macro UID(msgno) or if you
really feel like it the function index_getuid(msgno) from index.c.
Both of these require the mailbox to be selected. Otherwise you
can always just fetch it directly from the memory-mapped mailbox
index:
uid = ntohl(*((bit32 *)(mailbox->index_base + mailbox->start_offset +
(msgno - 1) * mailbox->record_size)));
(yeah, a bit unwieldy!)
Or there's the nice interface way:
struct index_record record;
mailbox_read_index_record(mailbox, msgno, &record);
uid = record.uid;
Which has the added benefit that it will work once I finish
writing crc32 support in and you can't go doing random memory
offset reads any more without missing out on the crc32 check.
