NAME

       sd_event_source_get_event - Retrieve the event loop of an event source

SYNOPSIS

       #include <systemd/sd-event.h>

       sd_event* sd_event_source_get_event(sd_event_source *source);

DESCRIPTION

       sd_event_source_get_event() may be used to retrieve the event loop object the event source object
       specified as source is associated with. The event loop object is specified when creating an event source
       object with calls such as sd_event_add_io(3) or sd_event_add_time(3).

RETURN VALUE

       On success, sd_event_source_get_event() returns the associated event loop object. On failure, it returns
       NULL.

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.

HISTORY

       sd_event_source_get_event() was added in version 229.
