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.
