# The Python win32clipboard lib functions work well enough ... except that they
# can only cut and paste items from within one application, not across
# applications or processes.
#
# I've written a number of Python text filters I like to run on the contents of
# the clipboard so I need to call the Windows clipboard API with global memory
# for my filters to work properly.
#
# Here's some sample code solving this problem using ctypes.
#
# This is my first work with ctypes. It's powerful stuff, but passing arguments
# in and out of functions is tricky. More sample code would have been helpful,
# hence this contribution.
