C Specification

To create an event, call:

// Provided by VK_VERSION_1_0
VkResult vkCreateEvent(
    VkDevice                                    device,
    const VkEventCreateInfo*                    pCreateInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkEvent*                                    pEvent);

Parameters

  • device is the logical device that creates the event.

  • pCreateInfo is a pointer to a VkEventCreateInfo structure containing information about how the event is to be created.

  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.

  • pEvent is a pointer to a handle in which the resulting event object is returned.

Description

When created, the event object is in the unsignaled state.

Valid Usage
Valid Usage (Implicit)
  • VUID-vkCreateEvent-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkCreateEvent-pCreateInfo-parameter
    pCreateInfo must be a valid pointer to a valid VkEventCreateInfo structure

  • VUID-vkCreateEvent-pAllocator-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • VUID-vkCreateEvent-pEvent-parameter
    pEvent must be a valid pointer to a VkEvent handle

Return Codes
On success, this command returns
  • VK_SUCCESS

On failure, this command returns
  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY
