小编Wya*_*att的帖子

我已经尝试了以下程序,但它在编译时告诉我"struct initializer中的值太少".

package main

/*
#include <stdlib.h>
struct Person {
    char *name;
    int age;
    int height;
    int weight;
};
*/
import "C"
import "fmt"

type p C.struct_Person

func main() {

    person := p{C.CString("Giorgis"), 30, 6, 175}
    fmt.Println(person)
    fmt.Println(C.GoString(person.name))
    fmt.Println(person.age)
    fmt.Println(person.height)
    fmt.Println(person.weight)
}

我该如何解决这个有线问题？另外,当我将类型"char*"更改为"char"和初始化程序时.它运作良好.

struct Person {
    char name;
    int age;
    int height;
    int weight;
};

另外,当我使用时

struct Person {
    char *name;
};

它也运作良好.

无论如何,我该如何解决？谢谢.

这是代码.在golang主函数中,在main.go中

func main() {
    rgc.GetRgcService()
}

其中,rgc在另一golang文件,命名mrgc.go.里面的代码是

package rgc
func GetRgcService() (svc *RgcService, err error) {}

函数GetRgcService是一个空函数.

但是,当我valgrind以前测试内存时,我得到了以下输出
