IO::Buffered

Return the buffer size used

Set the buffer size of both the read and write buffer Cannot be changed after any of the buffers have been allocated

Flushes and closes the underlying IO.

Flushes any buffered data and the underlying IO. Returns self.

Turns on/off flushing the underlying IO when a newline is written.

Determines if this IO flushes automatically when a newline is written.

Returns the bytes hold in the read buffer.

This method only performs a read to return peek data if the current buffer is empty: otherwise no read is performed and whatever is in the buffer is returned.

Returns the current position (in bytes) in this IO.

File.write("testfile", "hello")

file = File.new("testfile")
file.pos     # => 0
file.gets(2) # => "he"
file.pos     # => 2

Buffered implementation of IO#read(slice).

Turns on/off IO read buffering.

Determines whether this IO buffers reads.

Rewinds the underlying IO. Returns self.

Turns on/off IO write buffering. When sync is set to true, no buffering will be done (that is, writing to this IO is immediately synced to the underlying IO).

Determines if this IO does write buffering. If true, no buffering is done.

Closes the wrapped IO.

Flushes the wrapped IO.

TODO: Add return type restriction Nil

Reads at most slice.size bytes from the wrapped IO into slice. Returns the number of bytes read.

Rewinds the wrapped IO.

TODO: Add return type restriction Nil

Writes slice entirely into the wrapped IO.
