Holds progress of a cache management cleanup operation.
See also: CImCacheManager::ProgressL()
Number of messages processed so far.
Total number of messages to process.
Note that, immediately after a CImCacheManager object is started, the progress operation may return 1 for iTotalMessages and 0 for iMessagesProcessed, regardless of the total number of messages. This is because the counter for the iTotalMessages operates asynchronously and may not have counted all of the messages at that time.
