I did not make any progress. I tried
- in sendmsg_sendmsg to check for the right type arg (with PyErr_Format, got no
error)
- to print out the args with PySys_WriteStdout (did not get anything)
- I'm not even sure, if this error is related to my problem:
test_sendSubProcessFD ... [ERROR]
- If I try control_message->cmsg_type = 0;, I get Errno 22 in sendfd, as
expected
I need more pointers...
