=head1 NAME

MCE::Subs - Exports functions mapped directly to MCE methods

=head1 VERSION

This document describes MCE::Subs version 1.833

=head1 SYNOPSIS

 use MCE::Subs;  ## Exports manager and worker functions only
                 ## Getter functions are not exported by default

 use MCE::Subs qw( :getter  );  ## All, including getter functions
 use MCE::Subs qw( :manager );  ## Exports manager functions only
 use MCE::Subs qw( :worker  );  ## Exports worker functions only

 use MCE::Subs qw( :getter :worker );  ## Excludes manager functions

=head1 DESCRIPTION

This module exports functions mapped to MCE methods. All exported functions
are prototyped, therefore allowing one to call them without using parentheses.

 use MCE::Subs qw( :worker );

 sub user_func {
    my $wid = MCE->wid;

    mce_say "A: $wid";
    mce_sync;

    mce_say "B: $wid";
    mce_sync;

    mce_say "C: $wid";
    mce_sync;

    return;
 }

 MCE->new(
    max_workers => 24, user_func => \&user_func
 );

 mce_run 0 for (1..100);   ## 0 means do not shutdown after running

For the next example, we only want the worker functions to be exported due
to using MCE::Map, which takes care of creating a MCE instance and running.

 use MCE::Map;
 use MCE::Subs qw( :worker );

 ## The following serializes output to STDOUT and gathers $_ to @a.
 ## mce_say displays $_ when called without arguments.

 my @a = mce_map { mce_say; $_ } 1 .. 100;

 print scalar @a, "\n";

Unlike the native Perl functions, printf, print, and say methods require the
comma after the glob reference or file handle.

 MCE->printf(\*STDERR, "%s\n", $error_msg);
 MCE->print(\*STDERR, $error_msg, "\n");
 MCE->say(\*STDERR, $error_msg);
 MCE->say($fh, $error_msg);

 mce_printf \*STDERR, "%s\n", $error_msg;
 mce_print \*STDERR, $error_msg, "\n";
 mce_say \*STDERR, $error_msg;
 mce_say $fh, $error_msg;
