我如何获得JNA结构数组的C指针

Question

structTable是指向MyStruct的指针

MyStruct structs[3]; 
myobject.structTable = &structs[0]
myobject.structTableSize = 3;

我如何在Java中使用JNA？

Answer 1

含糊的问题。含糊的答案。如果您要创建新的/空的结构，则此方法应该起作用。

MyStruct struct = new MyStruct();
MyStruct[] structs = (MyStruct[]) struct.toArray(3);
myobject.structTable = structs; // Java Object pointing to structure array
long cPointer = Pointer.nativeValue(structs[0].getPointer()); // C pointer address
