RE: [Plib-devel] Another New Demo Program for PW

[Fay J. F C. AAC/W. <joh...@eg...>]

Steve,

	I have a couple of notes on your changes.  The first is that the
"%lf" is good for the "printf" statements but we need to be careful with the
"sscanf" statements.  I've put in a "float_value" variable which actually
gets read from the strings.

	The second is a PW issue which I think I raised earlier.  The fifth
argument of "pwInit" is "int multisample" which in the "pw_demo" program is
set to "false".  I think an "int" should be "TRUE" and "FALSE" rather than
the strict boolean values of "true" and "false".  I propose that we either
change the "pwInit" function to take a "bool" or else we change "pw.h" to
include definitions of "TRUE" and "FALSE" and change the sample programs to
pass those.  My personal preference is for the latter.

I eventually managed to compile this under Linux - there were a few
problems:

1) '%lf' is not allowed in printf's - the 'l' modifier can only be applied
    to integers - not doubles.  Just a plain '%f' is sufficient.

2) FALSE is undeclared in line 332.

3) The variable pargc isn't used.
