What is the meaning of an interpunct (·) in C?

Question

I´ve seen this in many popular C-Projects e.g the Go language and nowhere i can find some information about it. I think it is a kind of namespacing but i thought C doesn´t support it.

e.g

void runtime·memhash(uintptr*, uintptr, void*);

Thanks.

· is not a part of the "basic execution character set", and thus is not a standard C operator.

However, it does appear that the C standard allows it as an implementation-defined identifier character. It has no special meaning; it's just another character.
