set imap [new_CkImap]

# Turn on session logging:
CkImap_put_KeepSessionLog $imap 1

# Connect to an IMAP server.
# Use TLS
CkImap_put_Ssl $imap 1
CkImap_put_Port $imap 993
set success [CkImap_Connect $imap "imap.someMailServer.com"]
if {$success != 1} then {
    puts [CkImap_lastErrorText $imap]
    delete_CkImap $imap
    exit
}

# Login
set success [CkImap_Login $imap "myLogin" "myPassword"]
if {$success != 1} then {
    puts [CkImap_lastErrorText $imap]
    delete_CkImap $imap
    exit
}

# Select an IMAP mailbox
set success [CkImap_SelectMailbox $imap "Inbox.RubyMail"]
if {$success != 1} then {
    puts [CkImap_lastErrorText $imap]
    delete_CkImap $imap
    exit
}

# messageSet is a CkMessageSet

# Get the complete set of Uids for email in the selected mailbox.
set messageSet [CkImap_GetAllUids $imap]
if {[CkImap_get_LastMethodSuccess $imap] != 1} then {
    puts [CkImap_lastErrorText $imap]
    delete_CkImap $imap
    exit
}

# Set the Deleted flag for each message.
# (ExpungeAndClose must be called to finalize the delete.)
set success [CkImap_SetFlags $imap $messageSet "Deleted" 1]
if {$success != 1} then {
    puts [CkImap_lastErrorText $imap]
    delete_CkImap $imap
    exit
}

# Alternatively, the Deleted flag may be set for each UID
# individiually, but this is less efficient:

set n [CkMessageSet_get_Count $messageSet]
for {set i 0} {$i <= [expr $n - 1]} {incr i} {
    set success [CkImap_SetFlag $imap [CkMessageSet_GetId $messageSet $i] [CkMessageSet_get_HasUids $messageSet] "Deleted" 1]
    if {$success != 1} then {
        puts [CkImap_lastErrorText $imap]
        delete_CkImap $imap
        exit
    }

}

# Expunge and close the mailbox.
set success [CkImap_ExpungeAndClose $imap]
if {$success != 1} then {
    puts [CkImap_lastErrorText $imap]
    delete_CkImap $imap
    exit
}

# Display the session log.
puts [CkImap_sessionLog $imap]

# Disconnect from the IMAP server.
set success [CkImap_Disconnect $imap]
