Detailed Description

An object handling a collection of callbacks for the Android lifecycle.

Member Function Documentation

android_lifecycle_callbacks_create()

struct android_lifecycle_callbacks * android_lifecycle_callbacks_create

(

struct xrt_instance_android *

xinst_android

)

Create an android_lifecycle_callbacks object.

Parameters

xinst_android

The instance that will be passed to all callbacks.

android_lifecycle_callbacks_destroy()

void android_lifecycle_callbacks_destroy

(

struct android_lifecycle_callbacks **

ptr_callbacks

)

android_lifecycle_callbacks_register_callback()

int android_lifecycle_callbacks_register_callback	(	struct android_lifecycle_callbacks *	alc,
		xrt_android_lifecycle_event_handler_t	callback,
		enum xrt_android_lifecycle_event	event_mask,
		void *	userdata
	)

Register a lifecycle event callback.

Parameters

alc	Pointer to self
callback	Function pointer for callback
event_mask	bitwise-OR of one or more values from xrt_android_lifecycle_event
userdata	An opaque pointer for use by the callback. Whatever you pass here will be passed to the callback when invoked.

Returns

0 on success, <0 on error.

android_lifecycle_callbacks_remove_callback()

int android_lifecycle_callbacks_remove_callback	(	struct android_lifecycle_callbacks *	alc,
		xrt_android_lifecycle_event_handler_t	callback,
		enum xrt_android_lifecycle_event	event_mask,
		void *	userdata
	)

Remove a lifecycle event callback that matches the supplied parameters.

Parameters

alc	Pointer to self
callback	Function pointer for callback
event_mask	bitwise-OR of one or more values from xrt_android_lifecycle_event
userdata	An opaque pointer for use by the callback, must match the one originally supplied

Returns

number of callbacks removed (typically 1) on success, <0 on error.
