//  Function Macro: DECLARE_API(...)
//
//  Synopsis:   definition for an NTSD debugger extension function
//
//  Effects:
//
//  Arguments:  [hCurrentProcess]   - Handle to current process
//              [hCurrentThread]    - Handle to current thread
//              [dwCurrentPc]       - Copy of the program counter
//              [lpExtenisonApis]   - pointer to NTSD_EXTENSION_APIS
//                                    (structure function pointers for NTSD)
//              [args]              - a string of arguments from NTSD cmd line
//
//  Requires:
//
//  Returns:    void
//
//  Signals:
//
//  Modifies:

//  Notes:
//              we use a function macro for defining our debugger extensions
//              functions to allow for easy extensibility
//
//              !!!function names MUST be lower case!!!
