sequence number to uid conversion

[Toschi Pietro]

Hi
For an experiment I'm working at, I need to modify imapd.c so that COPY
and STORE commands are registered via syslog along with UIDs of messages
they apply to. It seems an easy job when clients issue commands
prepended with UID (eg. UID STORE <args>, UID COPY <args>), but I can't
face any way to convert a message sequence number to a message UID when
using the simple form. Is there some function and data structure that I
can use to obtain a message UID given a folder and a message sequence
number?

Thanks

Pietro
