Hello!
I've returned to SA:MP after quite some time now and I checked a script and found this.

PHP Code:

stock SendClientMessageEx(playerid, color, const text[], {Float, _}:...)
{
    static
        args,
        str[144];
    if ((args = numargs()) == 3)
    {
        SendClientMessage(playerid, color, text);
    }
    else
    {
        while (--args >= 3)
        {
            #emit LCTRL 5
            #emit LOAD.alt args
            #emit SHL.C.alt 2
            #emit ADD.C 12
            #emit ADD
            #emit LOAD.I
            #emit PUSH.pri
        }
        #emit PUSH.S text
        #emit PUSH.C 144
        #emit PUSH.C str
        #emit PUSH.S 8
        #emit SYSREQ.C format
        #emit LCTRL 5
        #emit SCTRL 4
        SendClientMessage(playerid, color, str);
        #emit RETN
    }
    return 1;
} 


From the usages of it, I see that this function is used to send messages with "variables" instead of formatting it and then sending the formatted message.

I just don't get what this #emit does. I tried to search for an emit preprocessor for C/C++(so I can get a general answer rather than a samp-related one), but can't find any results(There is a _emit keyword, which is not what this is).

It would be greatly appreciated if someone can briefly explain to me what that is. No complicated topics since I am just 14.

Have a nice day.

EDIT: If there is a "non-emit" alternative to do this, please let me know.
