NAME¶

ll2_update_login_time - Writes an *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 an 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. It could also be NULL if the return value is -1. error should be freed by the caller.
