C Specification
When VkExportMemoryAllocateInfoNV::handleTypes includes
VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_NV, add a
VkExportMemoryWin32HandleInfoNV structure 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:
// Provided by VK_NV_external_memory_win32
typedef struct VkExportMemoryWin32HandleInfoNV {
VkStructureType sType;
const void* pNext;
const SECURITY_ATTRIBUTES* pAttributes;
DWORD dwAccess;
} VkExportMemoryWin32HandleInfoNV;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
pAttributesis a pointer to a WindowsSECURITY_ATTRIBUTESstructure specifying security attributes of the handle. -
dwAccessis aDWORDspecifying access rights of the handle.
Description
If this structure is not present, or if pAttributes is 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
