✨ SYNOPSIS

void assert_on_journal_thread (struct recovery_journal *journal , const char *function_name );

no return value, no drama — it's void, it just ✨checks✨ and vibes.

🎀 ARGUMENTS

  • journal — the journal. yeah. that one. the journal in question, the main character 👑
  • function_name — the name of the function that's doing the check (for logging). so when things go sideways, the logs can be like "hey, it was this function's idea" 😭
