// Exporting a small subset of libproc (macOS-specific) features.

// Ideally the "libproc" crate can be used. At the time of writing,
|
|
// libproc does not expose the proc_bsdshortinfo struct, therefore
|
|
// cannot provide the "parent process" information.

// See:

// https://github.com/osquery/osquery/blob/4.0.0/osquery/tables/system/darwin/processes.cpp

// The build system is disappointing and can't exclude this target from Linux
|
|
// builds. So let's ifdef out the entire file.
