NAME

VERSION

10

SYNOPSIS

12        use MCE::Subs;  ## Exports manager and worker functions only
13                        ## Getter functions are not exported by default
14
15        use MCE::Subs qw( :getter  );  ## All, including getter functions
16        use MCE::Subs qw( :manager );  ## Exports manager functions only
17        use MCE::Subs qw( :worker  );  ## Exports worker functions only
18
19        use MCE::Subs qw( :getter :worker );  ## Excludes manager functions
20

DESCRIPTION

22       This module exports functions mapped to MCE methods. All exported
23       functions are prototyped, therefore allowing one to call them without
24       using parentheses.
25
26        use MCE::Subs qw( :worker );
27
28        sub user_func {
29           my $wid = MCE->wid;
30
31           mce_say "A: $wid";
32           mce_sync;
33
34           mce_say "B: $wid";
35           mce_sync;
36
37           mce_say "C: $wid";
38           mce_sync;
39
40           return;
41        }
42
43        MCE->new(
44           max_workers => 24, user_func => \&user_func
45        );
46
47        mce_run 0 for (1..100);   ## 0 means do not shutdown after running
48
49       For the next example, we only want the worker functions to be exported
50       due to using MCE::Map, which takes care of creating a MCE instance and
51       running.
52
53        use MCE::Map;
54        use MCE::Subs qw( :worker );
55
56        ## The following serializes output to STDOUT and gathers $_ to @a.
57        ## mce_say displays $_ when called without arguments.
58
59        my @a = mce_map { mce_say; $_ } 1 .. 100;
60
61        print scalar @a, "\n";
62
63       Unlike the native Perl functions, printf, print, and say methods
64       require the comma after the glob reference or file handle.
65
66        MCE->printf(\*STDERR, "%s\n", $error_msg);
67        MCE->print(\*STDERR, $error_msg, "\n");
68        MCE->say(\*STDERR, $error_msg);
69        MCE->say($fh, $error_msg);
70
71        mce_printf \*STDERR, "%s\n", $error_msg;
72        mce_print \*STDERR, $error_msg, "\n";
73        mce_say \*STDERR, $error_msg;
74        mce_say $fh, $error_msg;
