C Specification

The VkSemaphoreWaitInfo structure is defined as:

// Provided by VK_VERSION_1_2
typedef struct VkSemaphoreWaitInfo {
    VkStructureType         sType;
    const void*             pNext;
    VkSemaphoreWaitFlags    flags;
    uint32_t                semaphoreCount;
    const VkSemaphore*      pSemaphores;
    const uint64_t*         pValues;
} VkSemaphoreWaitInfo;

or the equivalent

// Provided by VK_KHR_timeline_semaphore
typedef VkSemaphoreWaitInfo VkSemaphoreWaitInfoKHR;

Members

  • sType is the type of this structure.

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

  • flags is a bitmask of VkSemaphoreWaitFlagBits specifying additional parameters for the semaphore wait operation.

  • semaphoreCount is the number of semaphores to wait on.

  • pSemaphores is a pointer to an array of semaphoreCount semaphore handles to wait on.

  • pValues is a pointer to an array of semaphoreCount timeline semaphore values.

Description

Valid Usage

  • VUID-VkSemaphoreWaitInfo-pSemaphores-03256
    All of the elements of pSemaphores must reference a semaphore that was created with a VkSemaphoreType of VK_SEMAPHORE_TYPE_TIMELINE

Valid Usage (Implicit)

  • VUID-VkSemaphoreWaitInfo-sType-sType
    sType must be VK_STRUCTURE_TYPE_SEMAPHORE_WAIT_INFO

  • VUID-VkSemaphoreWaitInfo-pNext-pNext
    pNext must be NULL

  • VUID-VkSemaphoreWaitInfo-flags-parameter
    flags must be a valid combination of VkSemaphoreWaitFlagBits values

  • VUID-VkSemaphoreWaitInfo-pSemaphores-parameter
    pSemaphores must be a valid pointer to an array of semaphoreCount valid VkSemaphore handles

  • VUID-VkSemaphoreWaitInfo-pValues-parameter
    pValues must be a valid pointer to an array of semaphoreCount uint64_t values

  • VUID-VkSemaphoreWaitInfo-semaphoreCount-arraylength
    semaphoreCount must be greater than 0
