String Formatting. - zT KiNgKoNg - 25.12.2014

I'm having an issue with a custom string formatting 'Stock', thats throwing out "error 047: array sizes do not match, or destination array is too small", Even though i'm using this kinda of system in a few more functions.

pawn Code:

stock CreateFormattedString(const msg[], {Float,_}:...)
{
    static
        string[268];

    if (numargs() == 1)
    {
        return msg;
    }
    else
    {
        new args = numargs();

        while (--args >= 1)
        {
            #emit LCTRL 5
            #emit LOAD.S.alt args
            #emit SHL.C.alt 2
            #emit ADD
            #emit ADD.C 12
            #emit LOAD.I
            #emit PUSH.pri
        }

        #emit PUSH.S msg
        #emit PUSH.C 268
        #emit PUSH.C string

        #emit LOAD.S.pri 8
        #emit PUSH.pri
        #emit SYSREQ.C format

        return string;

        #emit LCTRL 5
        #emit SCTRL 4
        #emit RETN
    }
}

This comment (especially the pdf excerpt) will explain as to why this error pops up. You can solve it like:

pawn Code:

if (numargs() == 1)
    {
        strcat((string[0] = EOS, string), msg);
        return string;
    }

(This is macroless strcpy)

There is other way using macros, but detecting single parameter is way more difficult than detecting none or more than 1.

Also you shouldn't edit assembly code (#emit) if you have no clue what you are doing
