I am doing a declaration of a structure, then passing the address of this
structure down to two functions deep
So you are in fact not passing structures but pointers...
#include <iostream>
using namespace std;
I strongly doubt that you got that through a C compiler before...
struct ModIO_ID_TAG {
int ADR_ModPos_1; //Bottom left
int ADR_ModPos_2; //Top left
int ADR_ModPos_3; //Bottom right
int ADR_ModPos_4; //Top right
} ModIO_ID;
....declaring a global object of name ModIO_ID.
void IOSS(struct ModIO_ID_TAG *ModIO_ID );
void IO_Interface(struct ModIO_ID_TAG *ModIO_ID);
....reusing the same name as function parameters.
void main()
main() returns int, by definition.
void IO_Interface(struct ModIO_ID_TAG *ModIO_ID)
{
int Pos1,Pos2,Pos3,Pos4;
IOSS(&ModIO_ID);
You either pass the same pointer(!) as Jochen already said or you at least
use the global properly. Alternatively, you could as well use a C compiler
instead of a C++ compiler. Renaming the file to .c will do this
automatically.
Another suggestion: you mentioned that you used this code on a different
compiler and it compiled there. In that case, I wonder if you either
ignored the warning or it simply didn't produce any. In the latter case,
you should (try to) activate warnings or raise the warning level.
