C Specification
The VkExternalMemoryProperties structure is defined as:
// Provided by VK_VERSION_1_1
typedef struct VkExternalMemoryProperties {
VkExternalMemoryFeatureFlags externalMemoryFeatures;
VkExternalMemoryHandleTypeFlags exportFromImportedHandleTypes;
VkExternalMemoryHandleTypeFlags compatibleHandleTypes;
} VkExternalMemoryProperties;
or the equivalent
// Provided by VK_KHR_external_memory_capabilities
typedef VkExternalMemoryProperties VkExternalMemoryPropertiesKHR;
Members
-
externalMemoryFeaturesis a bitmask of VkExternalMemoryFeatureFlagBits specifying the features ofhandleType. -
exportFromImportedHandleTypesis a bitmask of VkExternalMemoryHandleTypeFlagBits specifying which types of imported handlehandleTypecan be exported from. -
compatibleHandleTypesis a bitmask of VkExternalMemoryHandleTypeFlagBits specifying handle types which can be specified at the same time ashandleTypewhen creating an image compatible with external memory.
Description
compatibleHandleTypes must include at least handleType.
Inclusion of a handle type in compatibleHandleTypes does not imply the
values returned in VkImageFormatProperties2 will be the same when
VkPhysicalDeviceExternalImageFormatInfo::handleType is set to
that type.
The application is responsible for querying the capabilities of all handle
types intended for concurrent use in a single image and intersecting them to
obtain the compatible set of capabilities.
