[ctypes-commit] ctypes/ctypes/test test_loading.py,1.4,1.5 test_cfuncs.py,1.2,1.3

[Thomas H. <th...@us...>]

Update of /cvsroot/ctypes/ctypes/ctypes/test
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv22822

Modified Files:
	test_loading.py test_cfuncs.py 
Log Message:
On Windows, it is now possible to access functions exported by ordinal
by indexing the loaded dll with the ordinal number:

my_function = somedll[42]

To implement this, the signature of the _CFuncPtr class has changed.
_CFuncPtr can now be called with these arguments:

_CFuncPtr(integer address) -> foreign function
_CFuncPtr(callable) -> create a C callable function from callable

_CFuncPtr(integer index, method name) -> foreign function calling a COM method
_CFuncPtr((ordinal number, dll object), ...) -> foreign function exported by ordinal
_CFuncPtr((function name, dll object), ...) -> foreign function exported by name

WINFUNCTYPE and CFUNCTYPE are factory functions for _CFuncPtr subclasses,
so the above applies to the types returned from those as well.
