I just noticed that this swallows exceptions. It should have one of the "except" declarations at the end of the signature to enable proper exception signalling to the calling C/C++ code. http://docs.cython.org/src/userguide/language_basics.html#error-return-values > I have been using Cython for a period of time. But I can not find a > description for the "api" key word in Cython documents I admit that searching for "api" isn't really helpful here, but at least the page on "interfacing with external C code" shouldn't be all that hard to find in the given context. It contains this section: http://docs.cython.org/src/userguide/external_C_code.html#using-cython-declarations-from-c Stefan -- http://mail.python.org/mailman/listinfo/python-list
