C Specification
typedef struct XrEventDataInstanceLossPending {
XrStructureType type;
const void* XR_MAY_ALIAS next;
XrTime lossTime;
} XrEventDataInstanceLossPending;
Members
Receiving the XrEventDataInstanceLossPending event structure indicates
that the application is about to lose the indicated XrInstance at
the indicated lossTime
in the future.
The application should call xrDestroyInstance and relinquish any
instance-specific resources.
This typically occurs to make way for a replacement of the underlying
runtime, such as via a software update.
Description
After the application has destroyed all of its instances and their children
and waited past the specified time, it may then re-try xrCreateInstance
in a loop waiting for whatever maintenance the runtime is performing to complete.
The runtime will return XR_ERROR_INSTANCE_LOST
from xrCreateInstance
as long as it is unable to create the instance.
Once the runtime has returned and is able to continue, it must resume returning
XR_SUCCESS
from xrCreateInstance if valid data is passed in.
