I have a function whose definition looks like this: (vimg is a struct)

    void draw_vimg(vimg vectimg, int x, int y, int xscale, int yscale);

I want to pass it a vimg defined like so: (gen_vimg creates and sets initail
values for the struct)

    vimg *mygraphic;
    mygraphic = gen_vimg();

So I call draw_vimg like this:

    draw_vimg(mygraphic, 200, 100, 1, 1);

And I get errors like this:

    vector.cpp: In function `int main()':
    vector.cpp:45: conversion from `vimg *' to non-scalar type `vimg'
requested

So what can I do to send pointers to functions that call for variables, and
not pointers too the variables?

Thanks for your help. Philip.
