SD-HWDB(3)                       sd-hwdb                      SD-HWDB(3)

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.
