Hi,

I know this is off-topic because it's C-specific, but comp.lang.c discussion level seems to low, but comp.lang.c.moderated is all but dead and comp.std.c seems just as inappropriate. Please bear with me, here goes...

I have a public API like this:

extern "C" rettype api(param* p);

Now... This really is a mistake, it's an input parameter so it should have been:

extern "C" rettype api(const param* p);

Question: is this safe to do given that this is a public API and I don't control client code? Any downsides?

(To be frank: I am annoyed by GCC warnings in some old code, it's about char* and api("toto")).

TIA,

Goran.

Yes, it is safe, and should have no downsides as fa as I know.
