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
