Ensure enum name uniqueness in C without adding long prefix

Question

I find myself always appending the name of the enum, to its values, because else I often have conflicts with other enums, for example:

typedef enum
{
    A_ONE,
    A_TWO,
} A;

typedef enum
{
    B_ONE,
    B_TWO,
} B;

Is there a nicer way to do this in C?

Another example of the problem: `enum fruit { orange, apple, banana }; enum color { red, orange, yellow, green, blue, indigo, violet };` — Keith Thompson, Feb 01 '13 at 02:25

No, there is not. C++ has namespaces, or enums existing in classes (IIRC), but C is extremely primitive in this regard.

It is your own decision, but you can use the #define directive

#define WHAT_EVER TO_BE_REPLACED

Defines will be replaced from the WHAT_EVER in your code with TO_BE_REPLACED.

After your preprocessor run throw your code, all will be replaced.
