SYNOPSIS

16           use Test::Stream::Capabilities qw/CAN_FORK CAN_REALLY_FORK CAN_THREAD/;
17
18           if (CAN_FORK) {
19               my $pid = fork();
20               ...
21           }
22
23           if (CAN_REALLY_FORK) {
24               my $pid = fork();
25               ...
26           }
27
28           if (CAN_THREAD) {
29               threads->new(sub { ... });
30           }
31

DESCRIPTION

33       This module will export requested constants which will always be a
34       boolean true or false.
35

AVAILABLE CHECKS

37       CAN_FORK
38           True if this system is capable of true or psuedo-fork.
39
40       CAN_REALLY_FORK
41           True if the system can really fork. This will be false for systems
42           where fork is emulated.
43
44       CAN_THREAD
45           True if this system is capable of using threads.
46

NOTES && CAVEATS

48       5.10.0
49           Perl 5.10.0 has a bug when compiled with newer gcc versions. This
50           bug causes a segfault whenever a new thread is launched.
51           Test::Stream will attempt to detect this, and note that the system
52           is not capable of forking when it is detected.
53
54       Devel::Cover
55           Devel::Cover does not support threads. CAN_THREAD will return false
56           if Devel::Cover is loaded before the check is first run.
