(2)gcc编译生成动态库:gcc -o -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("./") lib.foo(1, 3) print('***finish***') 1. 2. 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...
