itoa(bla,bla,bla); ???

lets say i have an int function that ,, big suprise outputs an integer, then i have a text output in opengl that can only output char * , i found out i can convert the int to a char by using the itoa(); function but can someone please tell me if i'm doing this right

i get the integer from the function

int fpsint(CalculateFrameRate());

then i declare the char i want to store it in!

char *fps;

then i run itoa

itoa(fpsint,fps, 10);


should this not output fpsint to the char fps?

int fpsint = CalculateFrameRate();

I hope you've allocated memory for the char* also, which you haven't shown here.

do i do it like this fps=whatever[20];
and the int thing, i always thought it could be done that ways because it's like doing everything in one step, i was always tought to assign at least zero the the var from the start but thank you

you need something like
char fpsbuff[12] = "";
itoa(fps,fpsbuff,10);

the ="" is somewhat pointless, and I probably wouldn't do it in a fps calc where timing is so critical, but if you want to have an initial value, there ya go.
