identifier not found

If you want to customize the installer for Windows Mobile applications, you have to create C++ code.

I wanted to rename a file before the uninstall of a a previous version started.

codeUNINSTALL_INIT Uninstall_Init(HWND hwndParent, LPCTSTR pszInstallDir)
{
int result;
char oldname[] ="oldname.txt";
char newname[] ="newname.txt";
result = rename( oldname , newname );
return codeUNINSTALL_INIT_CONTINUE;
}

I was looking to add a file rename call in the Uninstall_Init, just a tweek from your coding example.
But I try to compile it I get

error C3861: 'rename': identifier not found

The includes in the .cpp file are:
#include <windows.h>
#include "stdio.h"
#include "ce_setup.h"

I haven't done C++ in 10 years and I'm pretty lost, I've searched/googled all day with no luck. Can anyone help me?

thanks,
Brian

Not sure about mobile apps. rename should be part of stdio.h (incidentally this should be <stdio.h> not "stdio.h"). Try

::rename(oldname, newname);

Thanks,
I made the change to <stdio.h>

and tried ::rename (oldname, newname);

and now I get:
Error 25 error C2039: 'rename' : is not a member of '`global namespace''

now I see the rename defined in stdio.h, I don't understand why it's not being found.

<stdio.h> header does not contain any namespaces (it's C-compatible header). It's <cstdio> declares C-part of C++ RTL in a global namespace.

Thanks out to everyone for your attempts to help me.

Here is what I found, inside cstdio

#if !defined(_WIN32_WCE)
// These are not supported on CE
using ::freopen; using ::getc; using :error;
using :utc;
using ::remove; using ::rename; using ::rewind;
using ::setbuf; using ::tmpfile; using ::tmpnam;
#endif

It appears, if I'm reading this right, that rename is not supported on the platform I've targeted.

I did solve my problem by using CopyFile
