As I think I understand from ctypes docs: Ctypes uses functions exposed in a shared library, macros existing only a header are not available. If its PyArray... is a macro then I a) need to compile and make a little library directly from arrayobject.h or b) need to use the root function upon which the macro is based, PyArrayNew?
ctypes has built-in access to the functions in the core python library, but Im not sure which library contains all the PyArray API calls, since its all typically hidden by distutils and setup.py Mark ------------------------------------------------------------------------- Using Tomcat but need to do more?
