C Union Kinds |
Use “c union” to match all C Union kinds.
A union allows storage of different types of data into the same storage area.
A union may be a member of a class. In this case the union may be private, protected, or public.
A union or member union may be unnamed.
An unresolved union is a union which is known to exist, but who’s definition is unknown. This typically occurs when a header file is not part of the project. An unknown union is a union whose definition and declaration is not found.
#include "my_unions.h" // C Unresolved Header File; union my_union data; // C Unresolved Union Type // my_union is defined in unresolved header file union unknown_union more_data; //unknown_union is not // defined and is C Unknown Type
