First the version of xmotor/wmotor in the archive is shrouded and will
only run in eu version 2.5

I have been using an unshrouded version with eu 3.1.x and it also works.

The main library ( motor.eu ) is the same one in both wmotor and xmotor.

The only difference between wmotor and xmotor is the demos and the include
files.

xmotor -- is used to write programs in x, xt, athena, open-motif, presently
I am playing around with using it with GTK.

wmotor -- is used for writing win32 code.

To write a cross-platform program you would need to use motor.eu to create
a wrapper library to use win32 code on windows and (motif or athena) to
emulate the same win32 code on Linux.

The advanage of motor.eu library is the ease of wrapping, shared libraries,
structures, even varible argument parameters, and other Linux support code.

To use some functions in windows:

library("kernel32.dll")
declare("ConnectNamedPipe",2,s)
declare("ContinueDebugEvent",3,s)
declare("ConvertDefaultLocale",1,u)
declare("ConvertThreadToFiber",1,u)
declare("CopyFileA",3,s)

To use some functions in Linux using XT:

library("libXt.so")
declare("XtAppAddWorkProc",3,u)
declare("XtAppAddConverter",6,n)
declare("XtScreenDatabase",1,u)
declare("XtAppSetSelectionTimeout",2,n)
declare("XtVaGetApplicationResources","..",n) <<-- Note a variable argument
parameter .
declare("XtIsObject",1,u)

I am also contemplating adding in line Assembler support in euphoria
functions.

I have thought about releasing unshrouded code to the archive but
how do I protect my original ideas from others claiming to have
them as their own after I have invested all my hard work to
discover my ideas.
