Can you document that the flag values are defined as SD_JOURNAL_FLAG_ and must be bitwise ORed

Why this an array? Just let the caller do the bitwise OR. I think the issue is that the default flag will be 0 but ensure we know a user explicitly set the flags converting it to pointer may be enough so *int,

Yes, I will continue working on this, but I won’t be able to do it ASAP. |

I needed to merge journals, which involves using the
--mergeflag when callingjournalctl. Since I couldn't find a way to do this in the current implementation, I propose the following solution.The structure
JournalReaderConfigis augmented with a fieldFlagsthat contains an array of constants. If theFlagsarray is not empty, the methodNewJournalWithFlagsis called with the bitwise OR of the values in the array.
