SD-VARLINK(3)                   sd-varlink                  SD-VARLINK(3)

NAME         top

       sd-varlink - APIs for Varlink IPC

SYNOPSIS         top

       #include <systemd/sd-varlink.h>

       pkg-config --cflags --libs libsystemd

DESCRIPTION         top

       sd-varlink.h is part of libsystemd(3) and provides APIs for
       implementing Varlink IPC clients and services. See
       https://varlink.org/ for more information about Varlink IPC.

       Varlink IPC uses JSON[1] as marshalling format. The sd-varlink API
       relies on the sd-json(3) API for JSON serialization,
       deserialization and manipulation.

       The varlinkctl(1) tool makes the functionality implemented by
       sd-varlink available from the command line.

NOTES         top

       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.
