2.Perl 多线程:Threads(线程返回值)

 1 use warnings;
 2 use strict;
 3 use threads;
 4  
 5 sub TEST{
 6     print "Hello, World!\n";
 7     return (qw/1 2 3 4 ‘a‘/);
 8 }
 9  
10 #返回列表方法1
11 my ($t1) = threads->new(‘TEST‘);
12 print $t1->join, "\n";
13  
14 #返回列表方法2
15 #
16 my $t2 = threads->new({‘context‘ => ‘list‘}, ‘TEST‘);
17 print $t2->join, "\n";
18  
19 #返回单个值
20 my $t3 = threads->new(‘TEST‘);
21 print $t3->join, "\n";
22 getc();

1 #eg.
2 my @values = &test;
3 #如果函数调用中返回列表， 如你用一个$value获得返回值， 应会得到列表的最后一个元素的值
4 #eg.
5 my $value = (1,2,3,4 ‘a‘);
6 print $value;
7 #result:‘a‘
8 #注意， 这跟my $value = 1,2,3,4, ‘a‘;不同
9 #
