In this noncompliant code example, the pointerptris converted to an integer value. The high-order 9 bits of the number are used to hold a flag value, and the result is converted back into a pointer. This example is noncompliant on an implementation where pointers are 64 bits and unsigned ...

跟pointer一样,引用也是一个对象,拥有自己的地址 ri = byref(i)ri # <cparam 'P' (0000000008B6BB10)> 这是对象ri的地址,并非i的地址 4、数组 ctypes的Array The recommended way to create concrete array types is by multiplying any ctypes data type with a positiveinteger. Alternatively, you can su...

解释编译器警告信息 "[-wint-to-pointer-cast]" 的含义 编译器警告信息 "[-wint-to-pointer-cast]" 表示在代码中进行了从整数类型到指针类型的转换,而这种转换在大小上是不匹配的。在C或C++中,整数类型和指针类型的大小可能因平台和编译器而异,特别是在32位和64位系统之间。如果直接将一个整数转换为指针,而...
