-
-=head1 SYNOPSIS
-
- use Tk::Event;
-
- Tk::Event->fileevent(\*FH, 'readable' => callback);
-
- Tk::Event->lineavail(\*FH, callback);
-
- use Tk::Event::Signal qw(INT);
-
- $SIG{'INT'} = callback;
-
- use Tk::Event::process;
-
- Tk::Event->proc($pid, callback);
-
- QueueEvent(callback [, position])

-=head1 DESCRIPTION
-
-
-That is better than nothing but still hard to use. Most scripts want higher
-level result (a line, a "block" of data etc.)
-
-So it has occured to me that we could use new-ish TIEHANDLE thus:
-
- my $obj = tie SOMEHANDLE,Tk::Event::IO;
-
- while (<SOMEHANDLE>)
- {
- }
-
-Then the READLINE routine registers a callback and looks something like:
-
- sub READLINE
- {
- my $obj = shift;
- Event->io(*$obj,'readable',sub { sysread(*$obj,${*$obj},1,length(${*$obj}) });
- my $pos;
- while (($pos = index(${*$obj},$/) < 0)
- {
- DoOneEvent();
- }
- Event->io(*$obj,'readable',''); # unregister
- $pos += length($/);
- my $result = substr(${*$obj},0,$pos);
- substr(${*$obj},0,$pos) = '';
- return $result;
- }
-
-This is using the scalar part of the glob representing the _inner_ IO
-as a buffer in which to accumulate chars.
