C Specification
Bits which can be set in
VkExternalImageFormatPropertiesNV::externalMemoryFeatures,
indicating properties of the external memory handle type, are:
typedef enum VkExternalMemoryFeatureFlagBitsNV {
VK_EXTERNAL_MEMORY_FEATURE_DEDICATED_ONLY_BIT_NV = 0x00000001,
VK_EXTERNAL_MEMORY_FEATURE_EXPORTABLE_BIT_NV = 0x00000002,
VK_EXTERNAL_MEMORY_FEATURE_IMPORTABLE_BIT_NV = 0x00000004,
VK_EXTERNAL_MEMORY_FEATURE_FLAG_BITS_MAX_ENUM_NV = 0x7FFFFFFF
} VkExternalMemoryFeatureFlagBitsNV;
Description
-
VK_EXTERNAL_MEMORY_FEATURE_DEDICATED_ONLY_BIT_NVspecifies that external memory of the specified type must be created as a dedicated allocation when used in the manner specified. -
VK_EXTERNAL_MEMORY_FEATURE_EXPORTABLE_BIT_NVspecifies that the implementation supports exporting handles of the specified type. -
VK_EXTERNAL_MEMORY_FEATURE_IMPORTABLE_BIT_NVspecifies that the implementation supports importing handles of the specified type.
