Re: something that would be nice

Without stating the obvious, is there any reason why you couldn't use a macro? OK its a bit clunky but it would work!

#define RETURN(x, y) {err_code = y; return(x);}

int err_code = 0;

char MyCharFunc(void)
{
  RETURN('c',1);
}

int MyIntFunc(void)
{
  RETURN(25, 2);
}

void main(void)
{
  char ch;
  int i;

  ch = MyCharFunc();
  printf ("\nAfter MyCharFunc() result is %c, err_code is %d", ch, err_code);
  i = MyIntFunc();
  printf ("\nAfter MyIntFunc() resut is %d, err_code is %d", i, err_code);
}

Just a thought

Hi,

My name is Matt Wells and I'm the sole creator of the internet's soon-to-be
largest search engine, http://www.gigablast.com/ .

I have many functions that return an integer value, positive, zero or
negative so I can't really say "this function returns -1 and 
sets errno on error" because -1 is a legit value for my
function to return. Passing in a pointer to the extra value(s) I would like
returned is, in my view, sloppy and potentially confusing.

So my question is... would it be easy to make functions return multiple
values?

For example:

main () {
    int value , myerrno ;
    value , myerrno = myfunction ( a,b,c );
    // or even
    ( value , myerrno ) = myfunction ( a , b , c );
}
int , int myfunction ( int a , int b , int c ) {
    return a + b + c , 0;
    // or
    return ( a + b + c , 0 );
}

This is more in line with mathematics, too. A function can map
an N dimensional point to an M dimensional point.

What do you guys think about this?

Is it a common request?

Matt
