NAME
vkDestroyEvent - Destroy an event object

C SPECIFICATION

    void vkDestroyEvent(
        VkDevice                                    device,
        VkEvent                                     event,
        const VkAllocationCallbacks*                pAllocator);

PARAMETERS

device
    Logical device which owns the object.

event
    The handle of the object to destroy.

DESCRIPTION

vkDestroyEvent destroys the event object whose handle is specified in event. event must be a valid handle to event object created through a successful call to vkCreateEvent on device. Attempts to destroy VK_NULL_HANDLE are silently ignored. After a event object has been destroyed, its handle becomes invalid and must not be accessed again. Results are undefined if a command buffer is waiting on a event when the event is destroyed.

VALID USAGE

    • device must be a valid VkDevice handle

    • If event is not VK_NULL_HANDLE, event must be a valid VkEvent handle

    • If pAllocator is not NULL, pAllocator must be a pointer to a valid VkAllocationCallbacks structure

    • If event is a valid handle, it must have been created, allocated or retrieved from device

    • Each of device and event that are valid handles must have been created, allocated or retrieved from the same VkPhysicalDevice

    • All submitted commands that refer to event must have completed execution

    • If VkAllocationCallbacks were provided when event was created, a compatible set of callbacks must be provided here

    • If no VkAllocationCallbacks were provided when event was created, pAllocator must be NULL

HOST SYNCHRONIZATION

    • Host access to event must be externally synchronized
