liblinux-pid-perl

Description

Perl already returns the PID and PPID in variables and builtins. Linux::Pid forces perl to call the underlying C functions getpid() and getppid().

This is useful with multithreaded programs. Linux' C library, using the Linux thread model, returns different values of the PID and the PPID from different threads.

A known consumer of this functionality is Apache2::SizeLimit (in libapache2-mod-perl2).
