VkExternalMemoryHandleTypeFlagBitsNV(3)

Name

VkExternalMemoryHandleTypeFlagBitsNV - Bitmask specifying external memory handle types

C Specification

Possible values of VkImportMemoryWin32HandleInfoNV::handleType, specifying the type of an external memory handle, are:

// Provided by VK_NV_external_memory_capabilities
typedef enum VkExternalMemoryHandleTypeFlagBitsNV {
    VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_NV = 0x00000001,
    VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT_BIT_NV = 0x00000002,
    VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_IMAGE_BIT_NV = 0x00000004,
    VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_IMAGE_KMT_BIT_NV = 0x00000008,
} VkExternalMemoryHandleTypeFlagBitsNV;

Description

  • VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT_BIT_NV specifies a handle to memory returned by vkGetMemoryWin32HandleNV.

  • VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_NV specifies a handle to memory returned by vkGetMemoryWin32HandleNV, or one duplicated from such a handle using DuplicateHandle().

  • VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_IMAGE_BIT_NV specifies a valid NT handle to memory returned by IDXGIResource1::CreateSharedHandle, or a handle duplicated from such a handle using DuplicateHandle().

  • VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_IMAGE_KMT_BIT_NV specifies a handle to memory returned by IDXGIResource::GetSharedHandle().
