C Specification

To create a semaphore, call:

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

Parameters

  • device is the logical device that creates the semaphore.

  • pCreateInfo is a pointer to an instance of the VkSemaphoreCreateInfo structure which contains information about how the semaphore is to be created.

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

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

Description

When created, the semaphore is in the unsignaled state.

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 success, this command returns
  • VK_SUCCESS

On failure, this command returns
  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY
