Is IFileDialog compatible with C?

Question speaks for itself. I have a program that used SHBrowseforfolder, but now they want me to upgrade it to IFileDialog which I made but is in C++, so is it even possible to get it to work with C since it's OOP?

This is C code to print the name of a selected folder using IFileDialog:

#include <shobjidl_core.h> //somewhere in your program
//...
IFileDialog *pfd;
IShellItem *psiResult;
PWSTR pszFilePath = NULL;
if (SUCCEEDED(CoCreateInstance(&CLSID_FileOpenDialog, NULL, CLSCTX_INPROC_SERVER, &IID_IFileOpenDialog, &pfd))){
  pfd->lpVtbl->SetOptions(pfd, FOS_PICKFOLDERS);
  pfd->lpVtbl->Show(pfd, hwnd);
  if (SUCCEEDED(pfd->lpVtbl->GetResult(pfd, &psiResult))){
    if (SUCCEEDED(psiResult->lpVtbl->GetDisplayName(psiResult, SIGDN_FILESYSPATH, &pszFilePath))){
      WCHAR *p = pszFilePath;
      while (*p){
        printf("%c",*p);//I don't like unicode
        p++;
      }
      CoTaskMemFree(pszFilePath);
    }
    psiResult->lpVtbl->Release(psiResult);
  }
  pfd->lpVtbl->Release(pfd);
}

IFileDialog is part of Microsoft's Component Object Model (COM). COM programming can be done in C. Quite tedious though.

Here's a tutorial (can't vouch for it's quality)
