Optional parameters - ReneG - 03.11.2012

What is the default value for optional parameters that are left empty with sscanf?

pawn Код:

CMD:ban(playerid, params[]) 
{
    if(!IsPlayerAdminEx(playerid, 3)) {
        return SendClientMessage(playerid, COLOR_GREY, "    You are not authorised to use that command!");
    }
    
    new 
        target,
        reason[20],
        days;
    
    if(sscanf(params, "usD", target, reason, days)) {
        return SendSyntaxMessage(playerid, "Leave days empty to permaban the player", "/ban [playerid] [reason] [days]");
    }
    
    BanAccount(target, ReturnNameEx(playerid), reason, days == -1 ? -1 : gettime() + (days * 86400));
    return 1;
}

I'm trying to insert -1 in the unbanstamp column if the player left "days" empty.

I'm asking what the default value of an optional integer is. I already know the sscanf specifiers.
