NAME ^

Child::Link::Proc - Proc object used by Child.

SEE ALSO ^

This class inherits from:

Child::Link

METHODS ^

$bool = $proc->is_complete()

Check if the child is finished (non-blocking)

$proc->wait()

Wait until child terminates, destroy remaining zombie process (blocking)

$proc->kill($SIG)

Send the $SIG signal to the child process.

NOTE: kill() is unpredictable on windows, strawberry perl sends the kill signal to the parent as well as the child.

$proc->pid()

Returns the process PID.

$proc->exit_status()

Will be undef unless the process has exited, otherwise it will have the exit status.

Note: When you call exit($N) the actual unix exit status will be bit shifed with extra information added. exit_status() will shift the value back for you. That means exit_status() will return 2 whun your child calls exit(2) see unix_exit() if you want the actual value wait() assigned to $?.

$proc->unix_exit()

When you call exit($N) the actual unix exit status will be bit shifed with extra information added. See exit_status() if you want the actual value used in exit() in the child.

HISTORY ^

Most of this was part of Parrallel::Runner intended for use in the Fennec project. Fennec is being broken into multiple parts, this is one such part.

FENNEC PROJECT ^

This module is part of the Fennec project. See Fennec for more details. Fennec is a project to develop an extendable and powerful testing framework. Together the tools that make up the Fennec framework provide a potent testing environment.

The tools provided by Fennec are also useful on their own. Sometimes a tool created for Fennec is useful outside the greator framework. Such tools are turned into their own projects. This is one such project.

Fennec - The core framework

The primary Fennec project that ties them all together.
