将返回的C数组转换为Python列表。可以使用ctypes提供的cast函数将缓冲区转换为指定类型的指针,然后使用列表推导式将其转换为Python列表。 完整的示例代码如下所示: 代码语言:txt 复制 from ctypes import * # 定义C函数的原型 get_array = CDLL("your_c_library.so").get_array get_array.argtypes = [POINTER...
ctypes是python内建的功能模块,可以用于解析binary文件,也可用于调用C/C++动态链接库函数的,后者使用广泛。 ctypes官方文档(docs.python.org/3/libra)是这样介绍的: ctypes is a foreign function library for Python.It provides C compatible data types, and allows calling functions in DLLs or shared libraries...

ctypes定义了一些和C兼容的基本数据类型: 构造函数接受任何具有真值的对象。 所有这些类型都可以通过使用正确类型和值的可选初始值调用它们来创建: >>> >>>c_int()c_long(0)>>>c_wchar_p("Hello, World")c_wchar_p(140018365411392)>>>c_ushort(-3)c_ushort(65533)>>> ...
