MPLAB XC8 C Compiler supports struct and
union types. Structures and unions only differ in the memory offset
applied to each member.
These types will be at least 1 byte wide. Bit-fields and
_Bool objects are fully supported.
The members of structures and unions
cannot be objects of type __bit.
Structures and unions can be passed freely as function arguments and function return values. Pointers to structures and unions are fully supported.
