# vkCreateEvent(3) Manual Page

## Name

vkCreateEvent - Create a new event object

## C Specification

To create an event, call:

    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 (Implicit)

- `device` must be a valid VkDevice handle

- `pCreateInfo` must be a valid pointer to a valid VkEventCreateInfo structure

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

- `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`
