A question for Rule8.3 - nyoshi - 02-10-2014
I have a question for an exception of Rule8.3.
I think that the structure "tab" of the following sample does not have compatibility.
Is this right?
Code:
[test1.c]
struct tab {
signed char a;
signed short b;
};
struct tab a;[test2.c]
Code:
struct tab {
signed char a;
signed short int b;
};
extern struct tab a;　/* non-compliant - incompatible version */Best Regards,
nyoshi

The exception to rule 8.3 allows compatible versions of the same basic type to be used interchangeably. This include basic types used within a structure declaration.
"signed short" and "signed short int" are compatible versions of the same basic type, which means the two versions of the "struct tab" are compatible.
