null :: IOData -> Bool #

Test whether IOData is empty

Since: 2.2.0

hGetContents :: Handle -> IODataMode -> IO IOData #

IOData Wrapper for hGetContents

Note: This operation uses lazy I/O. Use NFData to force all data to be read and consequently the internal file handle to be closed.

Since: 2.2.0

hPutContents :: Handle -> IOData -> IO () #

IOData Wrapper for hPutStr and hClose

This is the dual operation ot ioDataHGetContents, and consequently the handle is closed with hClose.
