sd-device - API for enumerating and introspecting local devices
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.
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.
