The "IO::Select" package implements an object approach to the system "select" function call. It allows the user to see what IO handles, see IO::Handle, are ready for reading, writing or have an exception pending....

"IO::Mux::Select" is a drop-in replacement for IO::Select that knows how to deal with IO::Mux::Handle handles. It also supports real handles so you can mix IO::Mux::Handle handles with real handles....

IO::Select::Trap is a wrapper for "IO::Select" which enables use of the "IO::Select->select()" method on IO::Scalar or IO::String object/filehandles. Other filehandle object types (ie IO::Socket) are passed through to IO::Select for processing. Most ...

This subclass of IO::Async::Loop uses the select(2) syscall to perform read-ready and write-ready tests. To integrate with an existing "select"-based event loop, a pair of methods "pre_select" and "post_select" can be called immediately before and af...

This is the default implementation of event loop for IO::Lambda. IO::Lambda is designed to be agnostic of event loop choice, but this one is the default, reference implementation. The module is not intended for direct use. The documentation declares ...

The "select" system call (and the "IO::Select" interface) allows us to process multiple streams simultaneously, blocking until one or more of them is ready for reading or writing. Unfortunately, this requires us to use "sysread" and "syswrite" rather...

This class uses IO::Async to dispatch requests. WARNING: This engine is still experimental. Patches welcome! In particular, this class definitely should cache connections....

"IO" provides a simple mechanism to load several of the IO modules in one go. The IO modules belonging to the core are: IO::Handle IO::Seekable IO::File IO::Pipe IO::Socket IO::Dir IO::Select IO::Poll Some other IO modules don't belong to the perl co...

IO::Pager can be used to locate an available pager and set the *PAGER* environment variable (see "NOTES"). It is also a factory for creating I/O objects such as IO::Pager::Buffered and IO::Pager::Unbuffered. IO::Pager subclasses are designed to progr...

Currently, Perl provides a somewhat clumsy way of manipulating the default filehandle, and no easy way of manipulating default error and input handles. This module serves the dual purpose of providing a means around this, as well as serving as a prot...

This module is based on Matt Sergeant's excellent Win32::ASP module, which can be found at <http://www.fastnetltd.ndirect.co.uk/Perl>. After using Mr. Sergeant's module, I took on the task of customizing and optimizing it for my own purposes. Feel fr...

The IO::DB library was created and is intended as a convenience library. It works by reducing clutter in your code caused by using the same redundant code. It also works under the philosophy of intelligent code. That is, let me tell you to do somethi...

This module implements asynchronous I/O using whatever means your operating system supports. It is implemented as an interface to "libeio" (<http://software.schmorp.de/pkg/libeio.html>). Asynchronous means that operations that can normally block your...

This is a class for null filehandles. Calling a constructor of this class always succeeds, returning a new null filehandle. Writing to any object of this class is always a no-operation, and returns true. Reading from any object of this class is alway...

"IO::Poll" is a simple interface to the system level poll routine....

"IO::React" provides an expect-like interface for interacting with whatever may be connected to a handle. The main routine is the "react" method, which calls subroutines based on matching patterns provided as arguments. There are four methods for con...

This collection of modules allows programs to be written that perform asynchronous filehandle IO operations. A typical program using them would consist of a single subclass of IO::Async::Loop to act as a container of other objects, which perform the ...

The epoll(4) subsystem is a new, (currently) Linux-specific variant of poll(2). It is designed to offer O(1) scalability over large numbers of watched file descriptors. You will need at least version 2.5.44 of Linux to use this module, and you might ...
