I have a 16-bit OS/2 application that I would like to recompile for 32-bit
OS/2.  This application currently uses KbdCharIn to retrieve keystrokes
from the keyboard.  There is no 32-bit version of KbdCharIn, though it
appears that DosDevIOCtl, Category 4, Function 74H, "Read Character Data
Records" may be a satisfactory substitute.

I have documentation for the 16-bit DosDevIOCtl in the form of Ray Duncan's
book and the include files for the 16-bit compiler, but all I have at the
moment for the 32-bit DosDevIOCtl are the include files for the 32-bit
compiler.  Both Duncan's book and the include file list five arguments to
the 16-bit DosDevIOCtl, but the 32-bit compiler's include file lists nine
arguments.  I've concluded that DosDevIOCtl has been changed and that I
need more documentation before attempting to determine whether DosDevIOCtl
will serve as a replacement for KbdCharIn.  Calling the 16-bit KbdCharIn
API from the 32-bit version of the program is an alternative that I'd like
to avoid, because my compiler doesn't support it at this time.

For a short term solution, can somebody tell me what the syntax is for the
32-bit DosDevIOCtl call?  For a long term solution, can somebody recommend
an OS/2 2.0 counterpart to Ray Duncan's book?
