NAME         top

       sd_event_source_get_event - Retrieve the event loop of an event
       source

SYNOPSIS         top

       #include <systemd/sd-event.h>

       sd_event* sd_event_source_get_event(sd_event_source *source);

DESCRIPTION         top

       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         top

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

NOTES         top

       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         top

       sd_event_source_get_event() was added in version 229.
