Help passing a reference to a pointer several times

[jblau]

I am trying to pass a reference through a couple of layers of
functions, and I am getting a C2664 Error.

Here is my setup:

I have a class [ c_ClassOne ] which contains a pointer to an object [
p_MyObject ].

I have a second class [ c_ClassTwo ] which has a function [
FunctionOne(MYOBJECTTYPE* myObject) ]


I have a third class [ c_ClassThree ] which also has a function [
FunctionTwo(MYOBJECTTYPE* myObject) ]


I then try to pass the reference to the pointer p_MyObject from
c_ClassOne to be used within FunctionTwo.

So in a function within c_ClassOne I create an instance of c_ClassTwo [
myClassTwo ]
I then pass a reference to p_MyObject as follows:
myClassTwo.FunctionOne(&p_MyObject);

Then within FunctionOne, I create an Instance of c_ClassThree [
myClassThree ]
I then attempt to once again pass the reference to p_MyObject:
myClassThree.FunctionTwo(&p_MyObject);

On that line I get the following error:
error C2664: 'CD3DInitialize::Enumerate' : cannot convert parameter 1
from 'LPDIRECT3D9 ** ' to 'LPDIRECT3D9'

Note: LPDIRECT3D9 is the Object Type of p_MyObject.


Can anyone explain what I am doing wrong, and help me understand how to
do it correctly?

Thanks,

Jody

Too many words... not enough code. Provide a compilable and minimal piece
of example code which shows your problem. Based on what you seem to have
described, you're not using C++ terminology correctly... you seem to be
freely swapping between "reference" and "pointer". They're not the same
thing. And you don't appear to be following your own coding standards.

You are not, you are passing the address of the pointer. Just pass it
on through if all of your functions take a MYOBJECTTYPE*.
