14 sd-hwdb.h is part of libsystemd(3) and allows read-only access the
15 systemd database of hardware properties. See hwdb(7) and systemd-
16 hwdb(8) for more information about the database.

18 See sd_hwdb_new(3) and sd_hwdb_get(3) for information about the
19 functions available.

22 Functions described here are available as a shared library, which can
23 be compiled against and linked to with the libsystemd pkg-config(1)
24 file.

26 The code described here uses getenv(3), which is declared to be not
27 multi-thread-safe. This means that the code calling the functions
28 described here must not call setenv(3) from a parallel thread. It is
29 recommended to only do calls to setenv() from an early phase of the
30 program when no other threads have been started.
