Io.output

Available since: Gideros 2011.6

Description

When called with a file name, it opens the named file (in text mode), and sets its handle as the default output file. When called with a file handle, it simply sets this file handle as the default output file. When called without parameters, it returns the current default output file.

In case of errors this function raises the error, instead of returning an error code.

(file) = io.output(file)
