Thanks, for the fix, now the function works, but unfortunately it's a dead end in the SWIG realm...Here's the statement: http://www.swig.org/Doc2.0/SWIGDocumentation.html#Python_nn18[...] However, the inverse operation is not possible, i.e., you can't build a SWIG pointer object from a raw integer value. [...]
PyCapsule https://docs.python.org/2/c-api/capsule.html, suggested by Federico seems a more viable approach:https://bfroehle.com/2011/07/18/python-capsules/ If Psycopg was able to retrieve a PyCapsule, XTA should be able to use it and the Python interpreter would be a gateway between two C/C++ distinct modules (Psycopg and XTA).I'm going to perform some experiments in the XTA wrapper before coming back to this mail thread.
