sd_event_source_get_event - Man Page

#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​.

All functions listed here are thread-agnostic and only a single thread may operate on a given object at any given time​. Different threads may access the same object at different times​. Multiple independent objects may be used from different threads in parallel​.

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​.

sd_event_source_get_event() was added in version 229​.
