C Specification

Bits which can be set in VkExternalImageFormatPropertiesNV::externalMemoryFeatures, indicating properties of the external memory handle type, are:

// Provided by VK_NV_external_memory_capabilities
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,
} VkExternalMemoryFeatureFlagBitsNV;

Description

  • VK_EXTERNAL_MEMORY_FEATURE_DEDICATED_ONLY_BIT_NV specifies 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_NV specifies that the implementation supports exporting handles of the specified type.

  • VK_EXTERNAL_MEMORY_FEATURE_IMPORTABLE_BIT_NV specifies that the implementation supports importing handles of the specified type.
