# vkDestroySemaphore(3) Manual Page

## Name

vkDestroySemaphore - Destroy a semaphore object

## C Specification

To destroy a semaphore, call:

    void vkDestroySemaphore(
        VkDevice                                    device,
        VkSemaphore                                 semaphore,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the logical device that destroys the semaphore.

- `semaphore` is the handle of the semaphore to destroy.

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

## Description

Valid Usage

- All submitted batches that refer to `semaphore` must have completed execution

- If `VkAllocationCallbacks` were provided when `semaphore` was created, a compatible set of callbacks must be provided here

- If no `VkAllocationCallbacks` were provided when `semaphore` was created, `pAllocator` must be `NULL`

Valid Usage (Implicit)

- `device` must be a valid `VkDevice` handle

- If `semaphore` is not VK_NULL_HANDLE, `semaphore` must be a valid `VkSemaphore` handle

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

- If `semaphore` is a valid handle, it must have been created, allocated, or retrieved from `device`

Host Synchronization

- Host access to `semaphore` must be externally synchronized
