What kind of macros are permissable?

Other than the fact that the macro below implies fixed size buffers, is
it unsafe to use?

#define MEMSET( __v__, __s__ ) memset( (__v__), 0x00, (__s__) )

I imagine there could be problems with the underscores as anything that
starts with two underscores is reserved for implementation use.

Such a macro doesn't imply a fixed size...it just does a cut and paste
routine in the code basically.

Correction: any name that _contains_ two consecutive underscores is
reserved by the implemenation. IOW, "v__" would also be reserved.
