C Specification

To create a semaphore, call:

VkResult vkCreateSemaphore(
    VkDevice                                    device,
    const VkSemaphoreCreateInfo*                pCreateInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkSemaphore*                                pSemaphore);


  • device is the logical device that creates the semaphore.

  • pCreateInfo is a pointer to a VkSemaphoreCreateInfo structure containing information about how the semaphore is to be created.

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

  • pSemaphore is a pointer to a handle in which the resulting semaphore object is returned.


Valid Usage (Implicit)
  • device must be a valid VkDevice handle

  • pCreateInfo must be a valid pointer to a valid VkSemaphoreCreateInfo structure

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

  • pSemaphore must be a valid pointer to a VkSemaphore handle

Return Codes

On failure, this command returns
