Golang1.7使用kernel32.dll 读取共享内存,代码小示例

package mainimport (    "fmt"    "syscall"    "unsafe")func main() {    ShareMemName, _ := syscall.BytePtrFromString("ShareMemory") //ShareMemory共享内存名称.    var sharememname = uintptr(unsafe.Pointer(ShareMemName))    kernet32 := syscall.NewLazyDLL("kernel32.dll")    OpenFileMapping := kernet32.NewProc("OpenFileMappingA")    ptr, _, err := OpenFileMapping.Call(0x0004, 0, sharememname) //0x0004 表示只读    if err.Error() != "The operation completed successfully." {        fmt.Println("This:", err)        return    }    ptr, err = syscall.MapViewOfFile(syscall.Handle(ptr), 0x0004, 0, 0, 0)    if err != nil {        fmt.Println("There:", err)        return    }    buf := *(*[60]byte)(unsafe.Pointer(ptr)) //我共享内存里面使用的是字符串所以这里映射成[:]byte array    fmt.Println(string(buf[:]))    err = syscall.UnmapViewOfFile(ptr)    fmt.Println(err)}
