I started studing C last monday so please don't acuse me for a too stupid way. Yesterday I wrote a "library" to read and write ini files which is ok. But in the h file I have a few functions that are used internally. Is there a way to make them unavailable to the other files that use this c file(like declaring them private as in VB)?
Thanks in advance

If you write the library as a class, you can have public and private sections.

can you do this in c? and how do you do it? I tried this function decleration in the .h file and it didn't work out

private char *clearchar(char *string, char *what);

You have to use a C++ class to do it, like this:

(Toggle Plain Text)

class OmgWtf {
public:
 int yey;
 char grr;
 OmgWtf();
protected:
 ~OmgWtf();
private:
 nottobeseen();
};

Bad example, but I think you get the idea.

I suggest you learn more C first before you get into C++ classes. They're not that difficult though.
And, just from my point of view, you should only use a class when it's needed (such as a game or large scale application.) Since it'll bloat your applications a bit.
