extern question

[JoeC]

I am trying to create a message box that allows you to enter a name
then display that name on a window. The program uses win32 but that is
not the issue. I want have a global buf variable. So that it can be
filled in the window then displayed in the main window.

Here is what I have

char * buf = NULL; //In my min program.

extern char * buf; // This is the section where I want buf displayed.

extern char * buf; //This is where I fill the array.
buf = new char[len];
GetDlgItemText(hwnd, IDC_NAME_EDIT, buf, len +1);


I have used extern before and it had made my progam possible but does
it work with a pointer?

I don't think this is a win32 issue.

Don't really need to see any further. It is highly unlikely you want to
either use:

char *
globals

Again I want to get data from one function to another and how best can
I do that?
