LL2_WRITE_ENTRY(3) Programmers Manual LL2_WRITE_ENTRY(3)
ll2_write_entry - Write a new entry into the database.
#include <lastlog2.h>
int ll2_write_entry (struct ll2_context *context, const char
*user, int64_t ll_time, const char *tty, const char *rhost, const
char *pam_service, char **error);
Writes an new entry into database, which is defined in context.
If context is NULL, the default database, defined in
LL2_DEFAULT_DATABASE, will be taken.
time_t login_time = time(0); // Get the system time
char *error = NULL;
const char *user = "root";
int ret = ll2_write_entry (NULL, user, login_time, "pts/0",
"192.168.122.1", NULL, &error);
pam_service is the service or instance name which has generated
the entry (optional).
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.
