NAME

       sd-varlink - APIs for Varlink IPC

SYNOPSIS

       #include <systemd/sd-varlink.h>

       pkg-config --cflags --libs libsystemd

DESCRIPTION

       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

       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.
