Overview

Package ioutil implements I/O utility functions.

Index

• func NewLimitedBufferReader(r io.Reader, n int) io.Reader
• func WriteAndSyncFile(filename string, data []byte, perm os.FileMode) error
• type ReaderAndCloser

Functions

func NewLimitedBufferReader

func NewLimitedBufferReader(r io.Reader, n int) io.Reader

NewLimitedBufferReader returns a reader that reads from the given reader but limits the amount of data returned to at most n bytes.

func WriteAndSyncFile

func WriteAndSyncFile(filename string, data []byte, perm os.FileMode) error

WriteAndSyncFile behaves just like ioutil.WriteFile in the standard library, but calls Sync before closing the file. WriteAndSyncFile guarantees the data is synced if there is no error returned.

Types

type ReaderAndCloser

type ReaderAndCloser struct {
	io.Reader
	io.Closer
}

ReaderAndCloser implements io.ReadCloser interface by combining reader and closer together.
