== 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.
