What's wrong with this:

[jimNLX]

#ifdef __cplusplus extern "C" { #endif typedef enum _DATA_TYPE { NONE_DATA, JP_DATA, DF_DATA, DATA_RANGE } DATA_TYPE; #ifdef __cplusplus } #endif

[David Crow]

Nothing syntactically. What do you think's wrong with it?

Five birds are sitting on a fence. Three of them decide to fly off. How many are left?

[jimNLX]

...h(81) : error C2011: '_DATA_TYPE' : 'enum' type redefinition

[David Crow]

Which means there's already a _DATA_TYPE defined someplace else. Put the cursor on it and press F12 should take you to the other definition.

Anybody have any ideas to help me resolve this problem? Thanks for any help
