sd_event_source_get_event — Retrieve the event loop of an event source
#include <systemd/sd-event.h>
sd_event* sd_event_source_get_event( | sd_event_source *source); |
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).
On success, sd_event_source_get_event()
returns the associated event loop object. On failure, it returns
NULL.
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.
