            my $name : shared;
            # Initiate a value
            my $location : shared = 'Tokyo';
            # you can also use 'pshared'
            my $favorite_programming_language : pshared = 'perl';
            # You can share array, hash and scalar
            my %preferences : shared;
            my @names : shared;

    2. calling "share"
            my( $name, %prefs, @middle_names );
            share( $name, %prefs, @middle_names );

    Once shared, you can use those variables normally and their values will
    be shared between the parent process and the asynchronous process.

    For example:

        my( $name, @first_names, %preferences );
        share( $name, @first_names, %preferences );
        $name = 'Momo Taro';

    The value of $SHARE_MEDIUM is automatically initialised to "memory" if
    the system, on which this module runs, supports IPC::SysV, or "mmap" if
    you have Cache::FastMmap installed, or else to "file"

  $SHARED_MEMORY_SIZE
    This is the size in bytes of the shared memory block used for sharing
    variables between the main process and the sub processes. This is used
    when you share variables, such as:

        my $name : shared;
        my( $name, %prefs, @middle_names );
        share( $name, %prefs, @middle_names );

    See "SHARED VARIABLES"

SERIALISATION
    Promise::Me uses the following supported serialiser to serialise shared
    data across processes:

    *   CBOR

    *   Sereal

            # Initiate a value

            # you can also use 'pshared'
            my $favorite_programming_language : pshared = 'perl';
            # You can share array, hash and scalar
            my %preferences : shared;
            my @names : shared;

:       my( $name, %prefs, @middle_names );
            share( $name, %prefs, @middle_names );

Once shared, you can use those variables normally and their values will
be shared between the parent process and the asynchronous process.

For example:

\$SHARED\_MEMORY\_SIZE
----------------------

This is the size in bytes of the shared memory block used for sharing
variables between the main process and the sub processes. This is used
when you share variables, such as:

        my $name : shared;
        my( $name, %prefs, @middle_names );
        share( $name, %prefs, @middle_names );

See [\"SHARED VARIABLES\"](#shared-variables){.perl-module}

SERIALISATION
=============

[Promise::Me](https://metacpan.org/pod/Promise::Me){.perl-module} uses
the following supported serialiser to serialise shared data across
processes:

lib/Promise/Me.pm  view on Meta::CPAN

    # Initiate a value
    my $location : shared = 'Tokyo';
    # you can also use 'pshared'
    my $favorite_programming_language : pshared = 'perl';
    # You can share array, hash and scalar
    my %preferences : shared;
    my @names : shared;

=item 2. calling L</share>

    my( $name, %prefs, @middle_names );
    share( $name, %prefs, @middle_names );

=back

Once shared, you can use those variables normally and their values will be shared between the parent process and the asynchronous process.

For example:

    my( $name, @first_names, %preferences );
    share( $name, @first_names, %preferences );
    $name = 'Momo Taro';

=head2 $SHARE_MEDIUM

The value of C<$SHARE_MEDIUM> is automatically initialised to C<memory> if the system, on which this module runs, supports L<IPC::SysV>, or C<mmap>, or else to C<file>

=head2 $SHARED_MEMORY_SIZE

This is the size in bytes of the shared memory block used for sharing variables between the main process and the sub processes. This is used when you share variables, such as:

    my $name : shared;
    my( $name, %prefs, @middle_names );
    share( $name, %prefs, @middle_names );

=head2 $USE_THREADS_SHARED

    my $data : shared = '';
