Subject: [ruby-talk:12988] Win32:  Wrapper functions?

Hi!  I've been using Ruby to learn the Win32 API on Windows 98.  Along the
way, I've found myself writing simple wrapper objects so I don't have to
make so many messy declarations.  This is an example (trimmed for E-mail):

# ---- Win32_Console.rb ----
STD_INPUT_HANDLE     = 0xFFFFFFF6
STD_OUTPUT_HANDLE    = 0xFFFFFFF5
STD_ERROR_HANDLE     = 0xFFFFFFF4

class Win32_Console
    require 'Win32API'

    def GetStdHandle( nStdHandle )
        a = Win32API.new( "kernel32", "GetStdHandle", ['l'], 'l' )
        a.call( nStdHandle )
    end

    def GetConsoleScreenBufferInfo( hConsoleOutput, lpBuffer )
        a = Win32API.new( "kernel32", "GetConsoleScreenBufferInfo", ['l',
'p'], 'i' )
        a.call( hConsoleOutput, lpBuffer )
    end
end

That way--with the class saved in my current directory--I can call things
like this:

# ---- test_Console.rb ----
require 'Win32_Console'
a = Win32_Console.new()
hnd = a.GetStdHandle( STD_OUTPUT_HANDLE )
lpBuffer = ' ' * 22
result = a.GetConsoleScreenBufferInfo( hnd, lpBuffer )
res = lpBuffer.unpack('SSSSSSSSSSS')
puts res
# and so on, and so forth

Because I've been using Ruby for about five days, I'm clueless.  Therefore,
I'll ask my questions here:

1.  Are there already Ruby Win32 API wrapper objects on the Web?  If so,
where can I find them?
2.  If there aren't such objects for download, is there an interest in such
a thing?
3.  If I exclaimed, "I have a module for everybody to use!" where would be
the best place to exclaim it?

Thanks in advance for your input, and have fun!

Michael
