C Specification

The VkSemaphoreGetSciSyncInfoNV structure is defined as:

// Provided by VK_NV_external_sci_sync
typedef struct VkSemaphoreGetSciSyncInfoNV {
    VkStructureType                          sType;
    const void*                              pNext;
    VkSemaphore                              semaphore;
    VkExternalSemaphoreHandleTypeFlagBits    handleType;
} VkSemaphoreGetSciSyncInfoNV;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • semaphore is the semaphore from which state will be exported.

  • handleType is the type of NvSciSync handle (NvSciSyncObj) representing the semaphore that will be exported.

Description

Valid Usage
  • VUID-VkSemaphoreGetSciSyncInfoNV-handleType-05122
    handleType must be VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SCI_SYNC_OBJ_BIT_NV

  • VUID-VkSemaphoreGetSciSyncInfoNV-semaphore-05123
    semaphore must have been created with a VkSemaphoreType of VK_SEMAPHORE_TYPE_TIMELINE

  • VUID-VkSemaphoreGetSciSyncInfoNV-semaphore-05129
    semaphore must have been created with VkExportSemaphoreSciSyncInfoNV included pNext chain of VkSemaphoreCreateInfo, or previously imported by vkImportSemaphoreSciSyncObjNV

Valid Usage (Implicit)
  • VUID-VkSemaphoreGetSciSyncInfoNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_SEMAPHORE_GET_SCI_SYNC_INFO_NV

  • VUID-VkSemaphoreGetSciSyncInfoNV-pNext-pNext
    pNext must be NULL

  • VUID-VkSemaphoreGetSciSyncInfoNV-semaphore-parameter
    semaphore must be a valid VkSemaphore handle

  • VUID-VkSemaphoreGetSciSyncInfoNV-handleType-parameter
    handleType must be a valid VkExternalSemaphoreHandleTypeFlagBits value
