Formatted string problem

[SuperSonic]

Hey guys! I have a deep question. I wanted to create my own version of the openUrl() function. Mine was supposed to do the same thing except that it would take in a formatted string like sprintf(). Here's the function I made:

Code: Select all

void url(const char *__format, ...)
{
    openUrl(__format);
}

Now of course, this deosn't work. Can anyone tell me how to fix it? A point will be your reward

Thanks!

just define it Like this maybe

Code: Select all

#define url openUrl


To use:

Code: Select all

url("url here");


it wont turn yeller' though.

Haha, that's not exactly what I mean. I want it so that I can do this:

Code: Select all

url("www.%s.com", "game-editor");

oh xD I get it. Quite simple actually. First create 2 variables, each char variables. named:

wName, fType

Now do this:

Code: Select all

void setWeb(char*webName, char*formatType)
{
    sprintf(wName, webName);
    sprintf(fType, formatType);
}



now you can do your function:
....

OH WAIT.. I see what you mean now!... nvm that is hard xD

Yeah, I know. But it would be so useful. Know what I mean?

Well, in that case it doesn't seem too necessary. As you would just use the sprintf beforehand. But, if you just wanted to be able to write custom urls with it, you could do something like this.

Code: Select all

void
url (char* first, char* second, char* third)
{
    char buffer[30];
    sprintf(buffer, "%s.%s.%s", first, second, third);
    openUrl(buffer);
}

The thing is in gE we can't use argument lists. The ellipse operator is supported, but you can't use the varg functions.

Aww, that's too bad

But I know I can do something like this in pure c++. Could you send me a pm how to do it? (if you have time)
