fsm_journal_eventfsm.h fsm.hfsm_journal_event void fsm_journal_event (int severity, int source, const char * file_source, const char * function_source, const char * string_value) It is mandatory for any event to call this function to be published in the journal. Before publication, a filter can be applied here (and only here) to select only some events of interest (during debugging, for example) If there are too many events, a filter can be applied here to select a few interesting events for publication in the log. This filter can operate on any the following five parameters: severity, source, *file_source, *function_source, *string_value. below (params) Simple filters (on a single parameter) can be combined using the logical operators 'and' and 'or' and parentheses.

fsm_journal_publication_requestfsm.h fsm.hfsm_journal_publication_request void fsm_journal_publication_request ( ) The fsm_journal_publication_request() is called only once, by main(), just after closing the app and before ending the program. This is to guarantee the chronological order of the events in the journal. The log is modified for each event but events can be send asynchronously. This is why the journal is only published once, before the end of "main()", Its chronological order is therefore guaranteed. src/journal.c/fsm_journal_publish() (called here) is the last function of the program to be executed. The fsm_struct_journal (gg_logs) is a static instance in this file. Therefore, all the functions that read or write it are in this file.
