Calling C from Python
License: Other
Comparing CFFI, Ctypes, Cython, CPPYY
A comparison of four ways to call from python into a c function. I show the advantages and disadvantages of all 4: boilerplate required, maintenance, speed.
If you read all the way through, there is a suprise at the end. No fair peeking.

Hi I was looking at this page https://github.com/mattip/c_from_python/blob/master/c_from_python.ipynb, and noticed the cppyy time was missing from the chart at the end and the copy time printing code was commented out too.
The section labelled "In [67]:" has the commented cppyy time.
The section labelled "Out[67]:" has the table with the missing cppyy time.
Function clock_gettime and constant definition CLOCK_PROCESS_CPUTIME_ID in file main.c are not part of the C standard library, but come from the POSIX C library. In order to avoid compilation problems on some (unlucky) machines, I suggest to avoid them.
