C Specification

The VkImportFenceWin32HandleInfoKHR structure is defined as:

// Provided by VK_KHR_external_fence_win32
typedef struct VkImportFenceWin32HandleInfoKHR {
    VkStructureType                      sType;
    const void*                          pNext;
    VkFence                              fence;
    VkFenceImportFlags                   flags;
    VkExternalFenceHandleTypeFlagBits    handleType;
    HANDLE                               handle;
    LPCWSTR                              name;
} VkImportFenceWin32HandleInfoKHR;

Members

  • sType is the type of 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.

  • flags is a bitmask of VkFenceImportFlagBits specifying additional parameters for the fence payload import operation.

  • handleType specifies the type of handle.

  • handle is the external handle to import, or NULL.

  • name is a null-terminated UTF-16 string naming the underlying synchronization primitive to import, or NULL.

Description

The handle types supported by handleType are:

Table 1. Handle Types Supported by VkImportFenceWin32HandleInfoKHR
Handle Type Transference Permanence Supported

VK_EXTERNAL_FENCE_HANDLE_TYPE_OPAQUE_WIN32_BIT

Reference

Temporary,Permanent

VK_EXTERNAL_FENCE_HANDLE_TYPE_OPAQUE_WIN32_KMT_BIT

Reference

Temporary,Permanent

Valid Usage
  • VUID-VkImportFenceWin32HandleInfoKHR-handleType-01457
    handleType must be a value included in the Handle Types Supported by VkImportFenceWin32HandleInfoKHR table

  • VUID-VkImportFenceWin32HandleInfoKHR-handleType-01459
    If handleType is not VK_EXTERNAL_FENCE_HANDLE_TYPE_OPAQUE_WIN32_BIT, name must be NULL

  • VUID-VkImportFenceWin32HandleInfoKHR-handleType-01460
    If handle is NULL, name must name a valid synchronization primitive of the type specified by handleType

  • VUID-VkImportFenceWin32HandleInfoKHR-handleType-01461
    If name is NULL, handle must be a valid handle of the type specified by handleType

  • VUID-VkImportFenceWin32HandleInfoKHR-handle-01462
    If handle is not NULL, name must be NULL

  • VUID-VkImportFenceWin32HandleInfoKHR-handle-01539
    If handle is not NULL, it must obey any requirements listed for handleType in external fence handle types compatibility

  • VUID-VkImportFenceWin32HandleInfoKHR-name-01540
    If name is not NULL, it must obey any requirements listed for handleType in external fence handle types compatibility

Valid Usage (Implicit)
  • VUID-VkImportFenceWin32HandleInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_IMPORT_FENCE_WIN32_HANDLE_INFO_KHR

  • VUID-VkImportFenceWin32HandleInfoKHR-pNext-pNext
    pNext must be NULL

  • VUID-VkImportFenceWin32HandleInfoKHR-fence-parameter
    fence must be a valid VkFence handle

  • VUID-VkImportFenceWin32HandleInfoKHR-flags-parameter
    flags must be a valid combination of VkFenceImportFlagBits values

Host Synchronization
  • Host access to fence must be externally synchronized
