用cgo在C中制作go字符串

#include "_cgo_export.h"

void createGoString(char* cString) {
    GoString goString = {cString, strlen(cString)};
    processGoString(goString);
}

package main

import "C"

//export processGoString
func processGoString(goString C.GoString) {
    // 在这里处理Go字符串
}

package main

// #cgo CFLAGS: -g -Wall
// #include <stdlib.h>
// void createGoString(char* cString);
// void processGoString(char* goString);
import "C"

package main

func main() {
    cString := C.CString("Hello, World!")
    defer C.free(unsafe.Pointer(cString))

    C.createGoString(cString)
}
