NAME

AnyEvent::Util - various utility functions.

SYNOPSIS

 use AnyEvent::Util;

DESCRIPTION

This module implements various utility functions, mostly replacing well-known functions by event-ised counterparts.

All functions documented without AnyEvent::Util:: prefix are exported by default.

fh_nonblocking $fh, $nonblocking

Sets the blocking state of the given filehandle (true == nonblocking, false == blocking). Uses fcntl on anything sensible and ioctl FIONBIO on broken (i.e. windows) platforms.

$guard = guard { CODE }

This function creates a special object that, when called, will execute the code block.

This is often handy in continuation-passing style code to clean up some resource regardless of where you break out of a process.

You can call one method on the returned object:

$guard->cancel

This simply causes the code block not to be invoked: it "cancels" the guard.
