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