os.StatFileInfo=os.Stat(“FileName”)通过得到FileName获取File所有的信息

package osimport "internal/testlog"
// Stat returns a FileInfo describing the named file.
// If there is an error, it will be of type *PathError.
func Stat(name string) (FileInfo, error) 
{ 
  testlog.Stat(name)

}

FileInfo = os.Stat(“FileName”)

// A FileInfo describes a file and is returned by Stat and Lstat.
type FileInfo interface { 
  Name() string       // base name of the file
  Size() int64        // length in bytes for regular files; system-dependent for others
