C Specification
To determine the image capabilities compatible with an external memory
handle type, add a VkPhysicalDeviceExternalImageFormatInfo structure
to the pNext
chain of the VkPhysicalDeviceImageFormatInfo2
structure and a VkExternalImageFormatProperties
structure to the
pNext
chain of the VkImageFormatProperties2 structure.
The VkPhysicalDeviceExternalImageFormatInfo
structure is defined as:
// Provided by VK_VERSION_1_1
typedef struct VkPhysicalDeviceExternalImageFormatInfo {
VkStructureType sType;
const void* pNext;
VkExternalMemoryHandleTypeFlagBits handleType;
} VkPhysicalDeviceExternalImageFormatInfo;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
handleType
is a VkExternalMemoryHandleTypeFlagBits value specifying the memory handle type that will be used with the memory associated with the image.
Description
If handleType
is 0, vkGetPhysicalDeviceImageFormatProperties2
will behave as if VkPhysicalDeviceExternalImageFormatInfo was not
present, and VkExternalImageFormatProperties will be ignored.
If handleType
is not compatible with the format
, type
,
tiling
, usage
, and flags
specified in
VkPhysicalDeviceImageFormatInfo2, then
vkGetPhysicalDeviceImageFormatProperties2 returns
VK_ERROR_FORMAT_NOT_SUPPORTED
.
