# vkSetEvent(3) Manual Page

## Name

vkSetEvent - Set an event to signaled state

## C Specification

To set the state of an event to signaled from the host, call:

    VkResult vkSetEvent(
        VkDevice                                    device,
        VkEvent                                     event);

## Parameters

- `device` is the logical device that owns the event.

- `event` is the event to set.

## Description

When vkSetEvent is executed on the host, it defines an event signal operation which sets the event to the signaled state.

If `event` is already in the signaled state when vkSetEvent is executed, then vkSetEvent has no effect, and no event signal operation occurs.

Valid Usage (Implicit)

- `device` must be a valid VkDevice handle

- `event` must be a valid VkEvent handle

- `event` must have been created, allocated, or retrieved from `device`

Host Synchronization

- Host access to `event` must be externally synchronized

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`
