    Consider this code...

    If I had:

    Code:
    #include <string.h>
    
    class someClass 
    {
    public:
    someClass();
    private:
    void strlen();
    };
    
    void someClass::strlen()
    {
     // do something like exit(0);
    }
    How could i use the strlen() defined in string.h ?

    If you want to use the strlen function directly with your class, that is so it could access private data of you class make it a friend by using the friend token. However the strlen() function is already defined so I'm not exactly sure what your asking.

    What is the purpose of
    void strlen();

    Well that was an example. I want to know how i can use native functions from a class with a member with the same name.

    In c++ you may have many functions that have the same name as long as their signatures are different, that is their argument list. Therefore you could use a function called strlen() as long as it had a different argument list from the one defined in the String header file. For example:
    Code:
    int DoThis(void);
    int DoThis(int, double);
    int DoThis(char *);
    These functions all have different signatures and are therefore allowed to have the same name. I hope this helps.

    std::strlen(/*whatever*/); or ::strlen(/*whatever*/); depending on how compliant your compiler is. Since you're including <string.h> it will probably be the latter. Try to make a habit out of using the new headers <cxxx> (so <string.h> becomes <cstring>).
