Missing compiler error?
PostPosted: Tue Sep 28, 2004 10:21 am     Reply with quote
Why doesn't this produce an error, or at least a warning? As far as I can tell, this declaration has no meaning and can't be accessed. I'm not even totally sure it's well-formed C.

Code:
#include <18F2320.h>

struct {
   int1 element1;
   int1 element2;
   int1 element3;
};

void main() {
}

It is absolutely correct. Your declaration is an anonym structure. It is commonly used in C e.g. in typedefs:

typedef stuct { // the struct has no name
int1 element1;
int1 element2;
int1 element3;
} myrec; // myrec is the name of the new type

The named version looks like this:
typedef stuct _tagMYREC { // tagMYREC is the name of the struct
int1 element1;
int1 element2;
int1 element3;
} myrec; // myrec is the name of the new type
