In a future post I’ll also deep dive into ctypes implementation in CPython, but for me to get to that, I need to cover the Python C API first in part 2 first, which makes the deep dive part 3. :)Anyway, let’s get started....
In my previous post we’ve briefly looked at using ctypes module to call C APIs. In this post let’s dive into a completely different approach - writing a C extension using Python/C API. From the C extension you can then call whatever C/C++ code you w...
针对你遇到的问题“python exception ignored on calling ctypes callback function”,我们可以从以下几个方面进行详细的分析和解答: 1. 理解问题背景 ctypes库: ctypes是Python的一个外部函数库,它提供了C兼容的数据类型,并允许调用DLLs或共享库中的函数。通过ctypes,你可以加载一个C库,然后调用其中的函数,就像它们...

We have the following issue on linux Ubuntu 20.04.5 (64x86): We load a DLL (librun.so) from a python script (test.py) using cpython. The DLL librun uses TBB and runs some simple parallel constructs in a task arena. When librun is unloade...
y=x.func_name(a,b,c) Will call the Fortran function with variablesa,b,cand returns the result iny. ywill be named tuple which contains (result, args). Whereresultis a python object for the return value (0 if a subroutine) and where args is a dict containing all arguments passed to...
