EV::IO

📦 max

An I/O watcher, as EV::io makes: its callback runs when a file handle is readable or writable. These methods change what it watches; the methods all watchers share are EV::Watcher’s.

Changing an active watcher stops and restarts it, losing its pending events.

Synopsis

my $w = EV::io $sock, EV::READ, \&on_read;
$w->events(EV::READ | EV::WRITE);    # also wait until writable
$w->set($other_sock, EV::READ);      # watch another handle

Functions

Configuration

set

Watch another handle, for other events: $w->set($fh, EV::READ). The handle may be a file handle or a descriptor number; one without a descriptor croaks illegal file descriptor or filehandle.

fh

The handle the watcher watches, as it was given; with an argument, watch that handle instead and return the old one.

events

The events the watcher waits for, EV::READ, EV::WRITE or both; with an argument, wait for those instead and return the old mask.
