file.go内容如下

package main/*#cgo linux LDFLAGS: -lrt#include <fcntl.h>#include <unistd.h>#include <sys/mman.h>#define FILE_MODE (S_IRUSR | S_IWUSR | S_IRGRP | S_IROTH)int my_shm_open(char *name) {    return shm_open(name, O_RDWR);    }*/import "C"import ("fmt""unsafe")func main() {// ...}

步骤如下：

1. go tool cgo file.go

2.go build file.go

3. ./file
