enum IO::Seek

Overview

Argument to a seek operation.

Defined in:

io.cr

Enum Members

Set = 0

Seeks to an absolute location

Current = 1

Seeks to a location relative to the current location in the stream

End = 2

Seeks to a location relative to the end of the stream (you probably want a negative value for the amount)
