Enum values from non-integer literals?

Is it possible in C to declare enum value开发者_运维技巧s from anything other than integer literals?

No. enums are constants with type int.

Just a small addition: http://en.wikipedia.org/wiki/Enumerated_type#C_and_syntactically_similar_languages

Any expression that is composed of integer literals in the broad sense (343, 'a', L'ß') other enum, and sizeof expressions.

I am not so sure but maybe also offsetof expressions.
