# MCE::Channel::ThreadsFast(3pm)

Fast channel for producer(s) and many consumers

## NAME

MCE::Channel::ThreadsFast - Fast channel for producer(s) and many consumers

## VERSION

This document describes MCE::Channel::ThreadsFast version 1.901

## DESCRIPTION

A channel class providing queue-like and two-way communication for threads only. Locking is handled using threads::shared.

This is similar to MCE::Channel::Threads but optimized for non-Unicode strings only. The main difference is that this module lacks freeze-thaw serialization. Non-string arguments become stringified; i.e. numbers and undef.

The API is described in MCE::Channel with the sole difference being `"send"` and `"send2"` handle one argument.

Current module available since MCE 1.877.

- new

  ```
   use MCE::Channel;
   # The default is tuned for one producer and many consumers.
   my $chnl_a = MCE::Channel->new( impl => 'ThreadsFast' );
   # Specify the 'mp' option for safe use by two or more producers
   # sending or receiving on the left side of the channel (i.e.
   # ->enqueue/->send or ->recv2/->recv2_nb).
   my $chnl_b = MCE::Channel->new( impl => 'ThreadsFast', mp => 1 );
  ```

## QUEUE-LIKE BEHAVIOR

- enqueue

  - dequeue

  - dequeue\_nb

  - end

  ## TWO-WAY IPC - PRODUCER TO CONSUMER

- send

  - recv

  - recv\_nb

  ## TWO-WAY IPC - CONSUMER TO PRODUCER

- send2

  - recv2

  - recv2\_nb

  ## LIMITATIONS

The t/04\_channel\_threads tests are disabled on Unix platforms for Perl less than 5.10.1. Basically, the MCE::Channel::ThreadsFast implementation is not supported on older Perls unless the OS vendor applied upstream patches (i.e. works on RedHat/CentOS 5.x running Perl 5.8.x).
