sd-device — API for enumerating and introspecting local devices
#include <systemd/sd-device.h>
pkg-config --cflags --libs libsystemd 
sd-device.h is part of
    libsystemd(3) and
    provides an API to introspect and enumerate devices on the local system. It provides a programmatic
    interface to the database of devices and their properties mananaged by
    systemd-udevd.service(8).
    This API is a replacement for
    libudev(3) and
    libudev.h.
See
| sd_device_get_syspath(3), | 
| sd_device_ref(3) | 
for more information about the functions available.
Functions described here are available as a shared
  library, which can be compiled against and linked to with the
  libsystemd pkg-config(1)
  file.
The code described here uses
  getenv(3),
  which is declared to be not multi-thread-safe. This means that the code calling the functions described
  here must not call
  setenv(3)
  from a parallel thread. It is recommended to only do calls to setenv()
  from an early phase of the program when no other threads have been started.
