(2)gcc编译生成动态库libpycall.so:gcc -o libpycall.so -shared -fPIC pycall.c。使用g++编译生成C动态库的代码中的函数或者方法时,需要使用extern "C"来进行编译。 (3)Python调用动态库的文件:pycall.py import ctypes ll = ctypes.cdll.LoadLibrary lib = ll("./libpycall.so") lib.foo(1, 3) ...

Now that we’ve looked at library loading and function loading/calling, let’s take a look at how structure is implemented. Recall how you write a structure:highlight 複製 class VECTOR3(Structure): _fields_ = [("x", c_int), ("y", c_int), ("z...
ctypes允许Python创建回调函数并将其传递给C函数。 from ctypes import CFUNCTYPE, c_int # 定义回调函数类型 callback_func = CFUNCTYPE(c_int, c_int, c_int) # 在C函数中使用Python回调函数 def my_callback(a, b): return a + b c_function_that_needs_callback = some_library.function_requiring_...
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 want. This is a pretty popular approach to expose a 3rd party C library as python m...

close_callback, a lambda or function that is called when a websocket to a window closes (i.e. when the user closes the window). It should take two arguments; a string which is the relative path of the page that just closed, and a list of other websockets that are still open.Default...
