# NAME

getppid - get parent process ID

# SYNOPSIS

getppid

# DESCRIPTION

Returns the process id of the parent process.

Note for Linux users: on Linux, the C functions `getpid()` and `getppid()` return different values from different threads. In order to be portable, this behavior is not reflected by the perl-level function `getppid()`, that returns a consistent value across threads. If you want to call the underlying `getppid()`, you may use the CPAN module `Linux::Pid`.
