C Specification

The VkImportFenceSciSyncInfoNV structure is defined as:

// Provided by VK_NV_external_sci_sync, VK_NV_external_sci_sync2
typedef struct VkImportFenceSciSyncInfoNV {
    VkStructureType                      sType;
    const void*                          pNext;
    VkFence                              fence;
    VkExternalFenceHandleTypeFlagBits    handleType;
    void*                                handle;
} VkImportFenceSciSyncInfoNV;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • fence is the fence into which the state will be imported.

  • handleType specifies the type of handle.

  • handle is the external handle to import.

Description

The handle types supported by handleType are:

  • VUID-VkImportFenceSciSyncInfoNV-pNext-pNext
    pNext must be NULL

  • VUID-VkImportFenceSciSyncInfoNV-fence-parameter
    fence must be a valid VkFence handle
