multithreading - Perl 线程 - 从模块调用子例程 (pm)

Question

启动额外 perl 模块中定义的子例程线程的正确语法是什么？

perl 程序:

use strict;
use warnings;
use forks;
require testModule;

# before solution - thanks ysth!
# testModule->main will not work!
#my $thr1 = threads->new(\&testModule->main, "inputA_1", "inputB_1");
#my $thr2 = threads->new(\&testModule->main, "inputA_2", "inputB_2");

# solved
#my $thr1 = threads->new(\&testModule::main, "inputA_1", "inputB_1");
#my $thr2 = threads->new(\&testModule::main, "inputA_2", "inputB_2");
my @output1 = $thr1->join;
my @output2 = $thr2->join;

perl 模块 testModule.pm:

package testModule;
sub main{
    my @input = @_;
    #some code
    return ($output1, $output2)
}

testModule->main 的确切系统调用是什么？

提前致谢!

Answer 1

你几乎做对了:

...threads->new( \&testModule::main, "inputA_1", "inputB_1" );

-> 仅用于类/实例方法调用；如果您希望将其作为类方法调用(这将使 @input 获取类名以及“inputA_1”和“inputB_1”)，那么您可以这样做:

...threads->new( sub { testModule->main(@_) }, "inputA_1", "inputB_1" );
