static variables and functions in header files

static variables and functions in header files

[Alina Valea]

Hello,

Has anybody ever declared variables and functions as static
in header files (that will be included in several .c files)?
I've just seen this in a project and it puzzled me. Is it OK
to do it?

Thanks, Alina

Yes but you need to be aware of its meaning :-)

Do it with care. Be gentle with the code...

It won't usually cause any problems, but it's seldom a good idea.

What's the point in declaring identically-named (but distinct)
variables in each source file which includes a particular header?

In general, header files should only contain declarations; definitions
belong in the actual source (.c) files.
