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.
