Structures
VkExportMemoryAllocateInfo
Specify exportable handle types for a device memory object
When allocating memory whose payload may be exported to another process or
Vulkan instance, add a VkExportMemoryAllocateInfo structure to the
pNext
chain of the VkMemoryAllocateInfo structure, specifying
the handle types that may be exported.
The VkExportMemoryAllocateInfo structure is defined as:
typedef struct VkExportMemoryAllocateInfo {
VkStructureType sType;
const void* pNext;
VkExternalMemoryHandleTypeFlags handleTypes;
} VkExportMemoryAllocateInfo;
or the equivalent
typedef VkExportMemoryAllocateInfo VkExportMemoryAllocateInfoKHR;
sType
is a VkStructureType value identifying this structure.pNext
isNULL
or a pointer to a structure extending this structure.handleTypes
is zero or a bitmask of VkExternalMemoryHandleTypeFlagBits specifying one or more memory handle types the application can export from the resulting allocation. The application can request multiple handle types for the same allocation.
Valid Usage
VUID-VkExportMemoryAllocateInfo-handleTypes-00656
The bits in handleTypes
must be supported and compatible, as
reported by VkExternalImageFormatProperties or
VkExternalBufferProperties
Valid Usage (Implicit)
VUID-VkExportMemoryAllocateInfo-sType-sType
sType
must be VK_STRUCTURE_TYPE_EXPORT_MEMORY_ALLOCATE_INFO
VUID-VkExportMemoryAllocateInfo-handleTypes-parameter
handleTypes
must be a valid combination of VkExternalMemoryHandleTypeFlagBits values
