NAME

       ll2_update_login_time - Writes a *new* entry with updated login time.

SYNOPSIS

       #include <lastlog2.h>

       int ll2_update_login_time (struct ll2_context *context, const char *user, int64_t ll_time, char **error);

DESCRIPTION

       Writes a new entry to database, defined in context, for user user. Time is set by ll_time whereas the
       other values are taken from an already existing entry. If context is NULL, the default database, defined
       in LL2_DEFAULT_DATABASE, will be taken.

           char    *error = NULL;
           const   char *user = "root";
           int64_t login_time = time(0); // Get the system time;

           int ret = ll2_update_login_time (NULL, user, login_time, &error);

RETURN VALUE

       Returns 0 on success, -ENOMEM or -1 on other failure. error contains an error string if the return value
       is -1. error is not guaranteed to contain an error string, could also be NULL. error should be freed by
       the caller.
