Types

type File

type File struct {
	*os.File // 底层文件指针
	// contains filtered or unexported fields
}

文件指针池指针

func OpenWithPool

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

获得文件对象，并自动创建指针池

func (*File) Close

func (f *File) Close()

获得底层文件指针

type Pool

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

文件指针池

func New

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

func (*Pool) Close

func (p *Pool) Close()

关闭指针池

func (*Pool) File

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

获得一个文件打开指针
