      Expose functions like:

      const char*
mongocrypt_default_pid_file_path (void);

const char*
mongocrypt_default_domain_socket_path (void);

      Which returns the default PID file path a driver should use to spawn and connect to mongocryptd.

else if $HOME
    $HOME/.local/share/mongocryptd.pid
else
