An abstract mainloop API vtable

Fields

userdata: *mut c_void

A pointer to some private, arbitrary data of the main loop implementation.

io_new: Option<extern "C" fn(a: *const MainloopApi, fd: i32, events: IoEventFlagSet, cb: Option<IoEventCb>, userdata: *mut c_void) -> *mut IoEventInternal>

Creates a new IO event source object.

io_enable: Option<extern "C" fn(e: *mut IoEventInternal, events: IoEventFlagSet)>

Enables or disables IO events on this object.

io_free: Option<extern "C" fn(e: *mut IoEventInternal)>

Frees a IO event source object.

io_set_destroy: Option<extern "C" fn(e: *mut IoEventInternal, cb: Option<IoEventDestroyCb>)>

Sets a function that is called when the IO event source is destroyed. Use this to free the userdata argument if required.

time_new: Option<extern "C" fn(a: *const MainloopApi, tv: *const timeval, cb: Option<TimeEventCb>, userdata: *mut c_void) -> *mut TimeEventInternal>

Creates a new timer event source object for the specified Unix time.

time_restart: Option<extern "C" fn(e: *mut TimeEventInternal, tv: *const timeval)>

Restarts a running or expired timer event source with a new Unix time.

time_free: Option<extern "C" fn(e: *mut TimeEventInternal)>

Frees a deferred timer event source object.

time_set_destroy: Option<extern "C" fn(e: *mut TimeEventInternal, cb: Option<TimeEventDestroyCb>)>

Sets a function that is called when the timer event source is destroyed. Use this to free the userdata argument if required.

defer_new: Option<extern "C" fn(a: *const MainloopApi, cb: Option<DeferEventCb>, userdata: *mut c_void) -> *mut DeferEventInternal>

Creates a new deferred event source object.

defer_enable: Option<extern "C" fn(e: *mut DeferEventInternal, b: i32)>

Enables or disables a deferred event source temporarily.

defer_free: Option<extern "C" fn(e: *mut DeferEventInternal)>

Frees a deferred event source object.

defer_set_destroy: Option<extern "C" fn(e: *mut DeferEventInternal, cb: Option<DeferEventDestroyCb>)>

Sets a function that is called when the deferred event source is destroyed. Use this to free the userdata argument if required.

quit: Option<extern "C" fn(a: *const MainloopApi, retval: RetvalActual)>

Exits the main loop and return the specified retval.
