SD-DEVICE(3)                    sd-device                   SD-DEVICE(3)

NAME         top

       sd-device - API for enumerating and introspecting local devices

SYNOPSIS         top

       #include <systemd/sd-device.h>

       pkg-config --cflags --libs libsystemd

DESCRIPTION         top

       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.

NOTES         top

       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.
