NAME

revoutput - Reverse output strings sample extension

SYNOPSIS

@load "revoutput"

BEGIN { REVOUT = 1 } # Reverse all output strings

DESCRIPTION

The revoutput extension adds a simple output wrapper that reverses the
characters in each output line. It's main purpose is to show how to
write an output wrapper, although it may be mildly amusing for the
unwary.

EXAMPLE

    @load "revoutput"

    BEGIN {
        REVOUT = 1
        print "hello, world" > "/dev/stdout"
    }

The output from this program is:

    dlrow ,olleh

BUGS

This extension does not affect the default standard output.
