VkExternalImageFormatPropertiesNV

The VkExternalImageFormatPropertiesNV structure is defined as:

typedef struct VkExternalImageFormatPropertiesNV {
    VkImageFormatProperties imageFormatProperties;
    VkExternalMemoryFeatureFlagsNV externalMemoryFeatures;
    VkExternalMemoryHandleTypeFlagsNV exportFromImportedHandleTypes;
    VkExternalMemoryHandleTypeFlagsNV compatibleHandleTypes;
} VkExternalImageFormatPropertiesNV;

• imageFormatProperties will be filled in as when calling vkGetPhysicalDeviceImageFormatProperties, but the values returned may vary depending on the external handle type requested.
• externalMemoryFeatures is a bitmask of VkExternalMemoryFeatureFlagBitsNV, indicating properties of the external memory handle type (vkGetPhysicalDeviceExternalImageFormatPropertiesNV::externalHandleType) being queried, or 0 if the external memory handle type is 0.
• exportFromImportedHandleTypes is a bitmask of VkExternalMemoryHandleTypeFlagBitsNV containing a bit set for every external handle type that may be used to create memory from which the handles of the type specified in vkGetPhysicalDeviceExternalImageFormatPropertiesNV::externalHandleTypecan be exported, or 0 if the external memory handle type is 0.
• compatibleHandleTypes is a bitmask of VkExternalMemoryHandleTypeFlagBitsNV containing a bit set for every external handle type that may be specified simultaneously with the handle type specified by vkGetPhysicalDeviceExternalImageFormatPropertiesNV::externalHandleType when calling vkAllocateMemory, or 0 if the external memory handle type is 0. compatibleHandleTypes will always contain vkGetPhysicalDeviceExternalImageFormatPropertiesNV::externalHandleType
