returning multiple values from a function

For example if you want a function that modifies the values of 3 pointers then you need to declare double pointers as function parameters. If you write many lines with double pointers, the code will be very hard to understand; so is there any way you can return more than one value, for example 3 input variables and 2 output ones?

int * function(int *p,int **q,int **r)
{
  ...
  return p;
}

int main(){
  int *p,*q,*r;

  ...

  p=function(p,&q,&r);

  ...

  return 0;
}

Answer 1

You can put all the variables you want to modify in a structure and return that structure from the function.
Since a structure can hold any number of elements, You can return any number of elements from a function in this way.

Ofcourse, the any as all practical values will have a limit in practical environments.
