String manipulation question

[krreks]

I need to concatenate a string with a dynamic part (don't know what the %d's and it's likes are called)... And exactly the fact that I don't know the name of what I'm trying to do is what makes so hard to google it :)

What I wan't to look something like this in my head:

strcat(ret, "! [%d] %s", i, buf);
 

The code above won't work, but what will? I don't wan't to do a dozen of strcats either...

I hope somebody will point it out :)

Thanks in advance

You're not looking for sprintf(), are you?

To augment on the previous reply: sprintf() to the end of the buffer:

sprintf(ret+strlen(ret), "your format string here", a, b, c, d);
 

kind regards,

Hi.

The sprintf function was what I was looking for, I found it myself and the problem got solved :)

Thanks anyway!
