NAME
sd-hwdb - Read-only access to the hardware description database
SYNOPSIS
#include <systemd/sd-hwdb.h>
pkg-config --cflags --libs libsystemd
DESCRIPTION
sd-hwdb.h is part of libsystemd(3) and allows read-only access the
systemd database of hardware properties. See hwdb(7) and systemd-
hwdb(8) for more information about the database.
See sd_hwdb_new(3) and sd_hwdb_get(3) for information about the
functions available.
NOTES
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.
