type File struct {

	// contains filtered or unexported fields
}

文件指针池指针

func Open(path string, flag int, perm os.FileMode, expire ...int) (file *File, err error)

获得文件对象，并自动创建指针池(过期时间单位：毫秒)

func OpenFile(path string, flag int, perm os.FileMode, expire ...int) (file *File, err error)

Deprecated. See Open.

func (f *File) Close() error

获得底层文件指针(返回error是标准库io.ReadWriteCloser接口实现)

type Pool struct {
	// contains filtered or unexported fields
}

File pointer pool.

func New(path string, flag int, perm os.FileMode, expire ...int) *Pool

创建一个文件指针池，expire = 0表示不过期，expire < 0表示使用完立即回收，expire > 0表示超时回收，默认值为0表示不过期。注意过期时间单位为：毫秒。

func (p *Pool) Close()

关闭指针池

func (p *Pool) File() (*File, error)

获得一个文件打开指针
