There is a new section discussing alignment in the numpy 1.14 structured array docs, which has some hints about interfacing with C structs. These new 1.14 docs are not online yet on scipy.org, but in the meantime you can view them here:

The numpy dtype constructor takes an “align” keyword that will pad it for you. https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.dtype.html -CHB ___ NumPy-Discussion mailing list NumPy-Discussion@python.org
