Thread: Dereferencing Structures

Code:

typedef struct abc
	{
		int y;
		char *b;
	}abc, *abcptr;
abc x={2,"sdgare"};
void *a;


void function(void *data)
{
	a=data;
}


int main()
{
	function(&x);
	printf("%d",(abcptr)(a)->y);	
	return 0;
}

This code gives me an error:- error C2223: left of '->y' must point to struct/union

Could someone please tell me why and how to make it work?
Thanks in advance!

Your parentheses are wrong, it should be:

Code:

((abcptr)a)->y

Also, you should avoid using globals and using typedefs to disguise pointers needlessly.

Thanks for the help!
