LL2_IMPORT_LASTLOG(3)

okay bestie, welcome to LL2_IMPORT_LASTLOG(3) — yes, that's the title, and this is the Programmers Manual page for it 💖✨ we're importing an old lastlog file into the lastlog2 database, and honestly? iconic little migration moment 🦋

🎀 NAME 🎀

ll2_import_lastlog — imports old lastlog file. that's the whole assignment, periodt 💅

✨ SYNOPSIS ✨

       #include <lastlog2.h>

       int ll2_import_lastlog (struct ll2_context *context, const char
       *lastlog_file, char **error);

💖 DESCRIPTION 💖

so this function is basically the friend who shows up with a moving box: it imports all the entries from the lastlog_file file (lastlog(8)) into the lastlog2 database defined with context. If context is NULL, it takes the default database, which is defined in LL2_DEFAULT_DATABASE — fallback behavior, no cap 💫

here's the example from the page, keeping it cute and exact:

           char    *error = NULL;
           const   char *lastlog_path = "/var/log/lastlog";

           int ret = ll2_import_lastlog (NULL, lastlog_path, &error);

🫶 RETURN VALUE 🫶

Returns 0 on success, -ENOMEM or -1 on other failure. If the return value is -1, error contains an error string. But bestie, listen: error is not guaranteed to contain an error string — it could also be NULL — and error should be freed by the caller. so yes, clean up after yourself 💅
