[https://mp.weixin.qq.com/s/ydhK8HYuRD0lZazPsPxsvg] c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///...

The declaration of a variadic function uses an ellipsis as the last parameter, e.g. int printf(const char* format, ...); See variadic arguments for additional detail on the syntax and automatic argument conversions. 参数可变函数声明时,最后一个 参数 使用 三个点好 来表示。 示例: int printf...

In addition, if a function argument is explicitly declared to be a pointer type (such as POINTER(c_int)) in argtypes,an object of the pointed type (c_int in this case) can be passed to the function. ctypes will apply the required byref()conversion in this case automatically. ...
