SUMMARY
=======

Applications for Microsoft Windows developed with the Windows SDK may display an
error message box with the error:

  "Unexpected QuickWin Error"

MORE INFORMATION
================

There are several possible causes for this error:

- A QuickWin application caused an unexpected application error (UAE) or
  general protect (GP) fault.

- or -

- A Microsoft Windows-based application that is not a QuickWin application
  called a QuickWin function. If execution of a non-QuickWin application for
  Windows results in this error, one of the QuickWin functions was linked and
  executed in the application.

- or -

- Possible mismatch of memory model libraries (for example, building a large
  model application but using SLIBCEW, the small model library for Windows.)

- or -

- Possible stray function pointers that accidentally call one of the QuickWin
  stubs.

- or -

- You may have attempted to use an invalid file handle with one of the I/O
  functions.

The run-time libraries for Windows (SLIBCEW, MLIBCEW, CLIBCEW, and LLIBCEW)
contain stubs to the QuickWin functions. Therefore, the linker will not give an
error when linking with a QuickWin function from a non-QuickWin application for
Windows. However, when the function executes, an error message box with the
error "Unexpected QuickWin Error" will be displayed.

The following functions are in the QuickWin library:

  _fwopen                    _wgopen
  _inchar                    _wgsetactive
  _wabout                    _wmenuclick
  _wclose                    _wopen
  _wgclose                   _wsetexit
  _wgetexit                  _wsetfocus
  _wgetfocus                 _wsetscreenbuf
  _wgetscreenbuf             _wsetsize
  _wgetsize                  _wyield
  _wggetactive

For further information regarding QuickWin applications and the QuickWin
routines, refer to the Language Help file of Visual C++ or the Microsoft Visual
C++ "Run-Time Library Reference" manual.
