SD-VARLINK(3)                   sd-varlinkSD-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 oflibsystemd(3) and provides APIs for       implementing Varlink IPC clients and services. Seehttps://varlink.org/for more information about Varlink IPC.       Varlink IPC usesJSON[1] as marshalling format. The sd-varlink API       relies on thesd-json(3) API for JSON serialization,       deserialization and manipulation.       Thevarlinkctl(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 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.
