sscanf warning: Format specifier does not match parameter count. - DavidSparks - 20.01.2015

Hello guys.

Alright so I have a problem, when I start my server I get my log spammed by these.

Код:

sscanf warning: Format specifier does not match parameter count.

And I don't know where its coming from so it's pretty hard to solve it. So does anyone know how I can track it down and maybe solve it?

All help appreciated.

This happens when you do this:

pawn Код:

new id, secid;
if(sscanf(params, "dd", id))//missing one parameter..

It should happen when you do a command, try to investigate which command is it and fix it.

Can it be this one?

pawn Код:

CMD:pm(playerid, params[])
{
    new str[128], str2[128], id, Name1[MAX_PLAYER_NAME], Name2[MAX_PLAYER_NAME];
    if(sscanf(params, "us", id, str2))
    {
        SendClientMessage(playerid, COLOR_YELLOW, "Usage: /pm <id> <message>");
        return 1;
    }
    if(!IsPlayerConnected(id)) return SendClientMessage(playerid, COLOR_YELLOW, "ERROR: Player not connected");
    if(BlockPM[playerid] == id) return SendClientMessage(playerid, COLOR_YELLOW, "ERROR: You cannot pm this player because he has blocked you from doing so.");

Next time explain him that you have to specify the size of the string along with the specifier.

Yes, you need to

Also why are you using sscanf more than one, sscanf split the parameters into the parameters you choose, no need to use it again, I'm talking about "sscanf(params, "ds[128]", id, str2);"

Re: sscanf warning: Format specifier does not match parameter count. - LivingLikeYouDo - 20.01.2015

You need to define the size/cells of the string when using the 'variable' in sscanf.
The size must not be smaller than your original code you are implying on, or else you might get half of the code working.
The example above my post is correct.

Thanks for the help guys but it seems like the problem still occurs...

Remember that it's specially when I start the server not when I type any command.

Anyways, any other solution tips?

Download and configure CrashDetect, it'll print you where the error is.
