passing variables to subroutines in C

I always forget how to do it!

//declare variable globally
int TINF;

//in the subroutine use a * for a pointer, and then continue throughout
void epi_stats(int *TINF) {
*TINF = something;
}

//in the main program call the subroutine and assign the value using &
int main(int argc, char** argv) {
epi_stats(&TINF);
}
