如何从JNA中的“内存/指针”对象读取结构？

Question

I've been searching for an hour and still haven't found a way to do this. How do I read a structure from a memory/pointer object? I don't see any methods in Pointer to read a structure, and the only methods of Structure that read from memory are protected. I am trying to use a windows function that takes a pointer to a malloc'd structure array to store PHYSICAL_MONITOR's, which is why I need to do this.

Answer 1

Structure defines a Pointer -based constructor.

class MyStructure extends Structure {
    public MyStructure() { 
    } 
    public MyStructure(Pointer p) { 
        super(p);
        read();
    } 

See the JavaDoc for Structure for the available options to control how/when Java fields are synched from native memory.
