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.
