Predefined FileOpen, SaveAs, etc. in C?

Hope this is the right message board.
I have noticed that there are predefined dialog boxes in C++ for such things a OnFileOpen, OnFileSaveAs, etc. In a C program, are there similar predefined dialog boxes also and where may they be found? I have not found any reference to any, even in the 5 volume 1999 Win32 API series by Iseminger/Microsoft Press and other books; so does one have to program their own in C? Using VS C/C++ 6.0 from Microsoft.
Thank you in advance.

GetOpenFileName()
GetSaveFileName()
OPENFILENAME Structure

You'll find plenty of examples just by searching this board . I know I've see one just this week.

Here's the MSDN example as well.
