通过LLVM按参数传递结构 [英] Pass structure by parameter with LLVM

问题描述

是否可以通过参数传递结构?

Is it possible to pass structure by parameter ?

它与Cabi兼容吗?

基本上，我希望有一个C ++ POD，它将包含两个成员(该结构将是一个胖指针，带有一个指针和一个整数)，并且能够将该结构作为函数参数传递给调用指令(甚至调用C代码时).

Basically, I would like to have a C++ POD which would contain two members (the structure would be a fat pointer, with a pointer and an integer), and be able to pass this structure as function parameter in call instructions (even when calling C code).

我现在不使用胖指针(指针和整数分别在不同的函数参数中)，我想知道在开始大型重构之前是否有可能！

I'm not using fat pointer now (the pointer and the integer are each in a different function parameter), and I would like to know if it's possible before starting a pretty big refactoring !

推荐答案

当然可以.这是一个示例:

Absolutely, you can. Here's an example:

struct MyStruct_t {
    char *charPointer;
    int number;
};

void myFunction(MyStruct_t myStructAsParam) {

    printf("String: %s, Number: %i", myStructAsParam.charPointer, myStructAsParam.number);
    // Your stuff here.
}
