Functions

func ConsistentRead

func ConsistentRead(filename string, attempts int) ([]byte, error)

ConsistentRead repeatedly reads a file until it gets the same content twice. This is useful when reading files in /proc that are larger than page size and kernel may modify them between individual read() syscalls.

func ReadAtMost

func ReadAtMost(r io.Reader, limit int64) ([]byte, error)

ReadAtMost reads up to `limit` bytes from `r`, and reports an error when `limit` bytes are read.
