NAME

Linux::FD::Pid - PID file descriptors

VERSION

version 0.001

SYNOPSIS

 use Linux::FD::Pid
 
 my $fh = Linux::FD::Pid($pid)

METHODS

new($pid)

This creates a pidfd file descriptor that can be used to await the termination of a process. This provides an alternative to using SIGCHLD, and has the advantage that the file descriptor may be monitored by select, poll, and epoll.

Note that it doesn't (and for now can't) do the actual waiting, one still needs waitpid for that.

send($signo)

This sends a signal to the process.
