C Specification
When VkExportMemoryAllocateInfoNV::handleTypes
includes
VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_NV
, add a
VkExportMemoryWin32HandleInfoNV
to the pNext
chain of the
VkExportMemoryAllocateInfoNV structure to specify security attributes
and access rights for the memory object’s external handle.
The VkExportMemoryWin32HandleInfoNV
structure is defined as:
typedef struct VkExportMemoryWin32HandleInfoNV {
VkStructureType sType;
const void* pNext;
const SECURITY_ATTRIBUTES* pAttributes;
DWORD dwAccess;
} VkExportMemoryWin32HandleInfoNV;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to an extension-specific structure. -
pAttributes
is a pointer to a WindowsSECURITY_ATTRIBUTES
structure specifying security attributes of the handle. -
dwAccess
is aDWORD
specifying access rights of the handle.
Description
If this structure is not present, or if pAttributes
is set to NULL
,
default security descriptor values will be used, and child processes created
by the application will not inherit the handle, as described in the MSDN
documentation for “Synchronization Object Security and Access Rights”1.
Further, if the structure is not present, the access rights will be
DXGI_SHARED_RESOURCE_READ
| DXGI_SHARED_RESOURCE_WRITE
