NAME        top

       sd-hwdb - Read-only access to the hardware description database

SYNOPSIS        top

#include <systemd/sd-hwdb.h>pkg-config --cflags --libs libsystemd

DESCRIPTION        top

       sd-hwdb.h is part oflibsystemd(3) and allows read-only access the       systemd database of hardware properties. Seehwdb(7) andsystemd-hwdb(8) for more information about the database.       Seesd_hwdb_new(3) andsd_hwdb_get(3) for 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 thelibsystemd pkg-config(1) file.       The code described here usesgetenv(3), which is declared to be       not multi-thread-safe. This means that the code calling the       functions described here must not callsetenv(3) from a parallel       thread. It is recommended to only do calls tosetenv()from an       early phase of the program when no other threads have been       started.
