All exports are optional, you must specify subs to import.
($success, $error) = try { ... }
Eval the codeblock, return success or failure, and the error message. This code protects [email protected] and $!, they will be restored by the end of the run. This code also temporarily blocks $SIG{DIE} handlers.
protect { ... }
Similar to try, except that it does not catch exceptions. The idea here is to protect [email protected] and $! from changes. [email protected] and $! will be restored to whatever they were before the run so long as it is successful. If the run fails $! will still be restored, but [email protected] will contain the exception being thrown.
True if this system is capable of true or pseudo-fork.
True if the system can really fork. This will be false for systems where fork is emulated.
True if this system is capable of using threads.
Returns true if threads are enabled, false if they are not.
This will return the id of the current thread when threads are enabled, otherwise it returns 0.
my $file = pkg_to_file($package)
Convert a package name to a filename.


Perl 5.10.0 has a bug when compiled with newer gcc versions. This bug causes a segfault whenever a new thread is launched. Test2 will attempt to detect this, and note that the system is not capable of forking when it is detected.
Devel::Cover does not support threads. CAN_THREAD will return false if Devel::Cover is loaded before the check is first run.
