NAME

       Linux::Pid - Get the native PID and the PPID on Linux

SYNOPSIS

           use Linux::Pid;
           print Linux::Pid::getpid(), "\t", Linux::Pid::getppid(), "\n";

           use Linux::Pid qw(getpid getppid);
           print getpid(), "\t", getppid(), "\n";

DESCRIPTION

       Why should one use a module to get the PID and the PPID of a process where there are the
       $$ variable and the "getppid()" builtin ? (Not mentioning the equivalent "POSIX::getpid()"
       and "POSIX::getppid()" functions.)

       In fact, this is useful on Linux, with multithreaded programs. Linux' C library, using the
       linux thread model, returns different values of the PID and the PPID from different
       threads. (Other thread models such as NPTL don't have the same behaviour). This module
       forces perl to call the underlying C functions "getpid()" and "getppid()".
