6.1.4 Mapping for enumerated types

The C mapping of an IDL enum type is an unsigned, 32 bits wide integer. Each enumerator in an enum is defined in an anonymous enum with an appropriate unsigned integer value conforming to the ordering constraints.

For instance, the following IDL:

      module m {
        enum e {
          value1,
          value2
        };
      };

would map, according to the scoped names rules, into

      typedef uint32_t m_e;
      enum {
        m_value1 = 0
        m_value2 = 1
      };
