We should only need to put the attribute in the header, right?
IMO it actually makes more sense to be in the .c. Reason is that if we are going to change to be hidden by default and annotate the public ones, then we don't need to play with macros to hide them from other projects including the header.
A declaration for a private symbol should not be in an exported header so we know that all the functions in that header should actually be public.

but then if the header is exported, you need to export the definition of the macro as well.. and undef it when it's not for internal use. I've seen nasty things on projects that went this route, because then you not only depend on the compiler version you are compiled with, but you also need to keep the flexibility for other projects that are including you. Example:
#ifdef EAPI # undef EAPI #endif
#ifdef _WIN32 # ifdef EFL_BUILD # ifdef DLL_EXPORT # define EAPI __declspec(dllexport) # else # define EAPI # endif # else # define EAPI __declspec(dllimport) # endif # define EAPI_WEAK #else # ifdef __GNUC__ # if __GNUC__ >= 4 # define EAPI __attribute__ ((visibility("default"))) # define EAPI_WEAK __attribute__ ((weak)) # else # define EAPI # define EAPI_WEAK # endif # else # define EAPI # define EAPI_WEAK # endif #endif

I think we should really migrate to making them hidden by default and only export the ones we want. When drm_public was removed, it was basically a nop since the visibility was still set as default. I will take a look on this.
