    Function pointers in structure

    Hi,
    I have a function pointer in a structure like this-
    Code:
    typedef struct mystruct
    {
        int (*fp)(int,int);
    }mystruct;
    I initialize this func pointer in a function like this-
    Code:
    void Init(mystruct *handle,int (*my_fp)(int,int))
    {
        handle->fp=my_fp;
    }
    thenI'm trying to use this function pointer in another function, like this-
    Code:
    int func(mystruct *handle)
    {
       int c=handle->fp(1,2);
       return c;
    }
    Somehow, it is giving me a lot of syntax errors. Please tell me what I'm doing wrong here!

    Re: Function pointers in structure

    Glad it is working. However, you should try to post these questions in the C++ forums, rather than the more general algorithms and data structures forum. Those are a little more high traffic (more eyeballs!) and people more likely to know how to fix syntax problems.

    However! If you have questions about algorithms and data structures at a bit of a higher level, this is the right sub-forum.
