Offsetof: Standards, Implementation & Limitations

C's offsetof() macro is an ANSI C library feature found in stddef.h. It evaluates to the offset (in bytes) of a given member within a struct or union type, an expression of type size_t. The offsetof() macro takes two parameters, the first being a structure or union name, and the second being the name of a subobject of the structure/union that is not a…
