Question

my question is quite simple : how sp_session_relogin is working ?

Here is how I try to use it.

bool login(const char* login, const char* password, bool remember)
{
    if (remember) {
        sp_error err = sp_session_relogin(_session);
        if (err==SP_ERROR_OK) {
            return true;
        }
        if (!login||!password) {
            return false;
        }
    }

    sp_session_login(_session, login, password, remember, NULL);
    return true;
}

and I my application I first call

login(0,0,true);

and if it returns false I recall it like this

login(username,password,true);

(username and password are retrieved from a UI).
then if I quite the application and relaunched it the first call to login continue to return false.

Edited after the answer from iKenndac

I was calling sp_session_logout() but I was not waiting for the logout callback being called. I had it but it is not better.
Here is how my application is ending

if (_session) {
    if (_loggedin) {
        char buffer[1024];
        int ret = sp_session_remembered_user(_session,buffer,sizeof(buffer)); 
        if (ret>0) {
            printf("remembered user: %s\n",buffer);
        }
        sp_session_logout(_session);
        int msTilNext = 0;
        while(_loggedin) {
            sp_session_process_events(_session, &msTilNext);
        }
    }

    sp_session_release(_session);
    _session = 0;
}

sp_session_remembered_user correctly return my username. After logout I am waiting for the logout callback being called processing event with sp_session_process_events. When logout callback is called, _loggedin became false so the loop end. I release the session. And quite the application.

Do you see another mistake or missing stuff ? Any idea ?

Thanks.

When you quit your application, make sure you call sp_session_logout() and wait until the logout completion callback is fired before allowing the application to terminate. Otherwise you’re likely to get an incomplete cache which will cause sp_session_relogin() to fail.
