Typedef Documentation

anj_dm_reboot_callback_t

typedef void anj_dm_reboot_callback_t(void *arg, anj_t *anj)

Callback function type for handling the LwM2M Reboot resource (/3/0/4).

This function is invoked when the Reboot resource is executed by the LwM2M server. The user is expected to perform a system reboot after this callback returns.

Note

The Execute operation may be sent as a Confirmable message, so it is recommended to delay the reboot until the response is successfully sent.

Parameters

arg	Opaque argument passed to the callback.
anj	Anjay object reporting the status change.

Function Documentation

anj_dm_device_obj_install()

int anj_dm_device_obj_install	(	anj_t *	anj,
		anj_dm_device_obj_t *	device_obj,
		anj_dm_device_object_init_t *	obj_init
	)

Installs device object (/3) in DM.

Example usage:

static int reboot_cb(void *arg, anj_t *anj) {
    // perform reboot
}
...
anj_dm_device_obj_t dev_obj;
anj_dm_device_object_init_t dev_obj_init = {
    .manufacturer = "manufacturer",
    .model_number = "model_number",
    .serial_number = "serial_number",
    .firmware_version = "firmware_version",
    .reboot_handler = reboot_cb
};
anj_dm_device_obj_install(&anj, &dev_obj, &dev_obj_init);

Parameters

anj	Anjay object to operate on.
device_obj	Pointer to a device object structure. Must be non-NULL.
obj_init	Pointer to a device object's initialization structure. Must be non-NULL.

Returns

non-zero value on error (i.e. object is already installed), 0 otherwise.
