C Specification

The VkSemaphoreTypeCreateInfo structure is defined as:

// Provided by VK_VERSION_1_2
typedef struct VkSemaphoreTypeCreateInfo {
    VkStructureType    sType;
    const void*        pNext;
    VkSemaphoreType    semaphoreType;
    uint64_t           initialValue;
} VkSemaphoreTypeCreateInfo;
// Provided by VK_KHR_timeline_semaphore
// Equivalent to VkSemaphoreTypeCreateInfo
typedef VkSemaphoreTypeCreateInfo VkSemaphoreTypeCreateInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • semaphoreType is a VkSemaphoreType value specifying the type of the semaphore.

  • initialValue is the initial payload value if semaphoreType is VK_SEMAPHORE_TYPE_TIMELINE.

Description

To create a semaphore of a specific type, add a VkSemaphoreTypeCreateInfo structure to the VkSemaphoreCreateInfo::pNext chain.

If no VkSemaphoreTypeCreateInfo structure is included in the pNext chain of VkSemaphoreCreateInfo, then the created semaphore will have a default VkSemaphoreType of VK_SEMAPHORE_TYPE_BINARY.
