由于 Go 不支持打包結構，我發現這篇很棒的文章通過示例解釋了如何在 go 中使用打包結構。https://medium.com/@liamkelly17/working-with-packed-c-structs-in-cgo-224a0a3b708b問題是當我嘗試 char * 代替 [10]char 時，它不起作用。我不確定這種轉換如何與 [10]char 而不是 char * 一起使用。這是取自上述文章并用 char * 修改的示例代碼。package main/*#include "stdio.h"#pragma pack(1)typedef struct{    unsigned char a;    char b;    int c;    unsigned int d;    char *e; // changed from char[10] to char *}packed;void PrintPacked(packed p){    printf("\nFrom C\na:%d\nb:%d\nc:%d\nd:%d\ne:%s\n", p.a, p.b, p.c, p.d, p.e);}*/import "C"import (    "bytes"    "encoding/binary")//GoPack is the go version of the c packed structuretype GoPack struct {    a uint8    b int8    c int32    d uint32    e [10]uint8}//Pack Produces a packed version of the go structfunc (g *GoPack) Pack(out *C.packed) {    buf := &bytes.Buffer{}    binary.Write(buf, binary.LittleEndian, g)    *out = *(*C.packed)(C.CBytes(buf.Bytes()))}func main() {    pack := &GoPack{1, 2, 3, 4, [10]byte{}}    copy(pack.e[:], "TEST123")    cpack := C.packed{} //just to allocate the memory, still under GC control    pack.Pack(&cpack)    C.PrintPacked(cpack)}我是第一次與 cgo 合作，所以如果我在任何時候錯了，請糾正我。
