VkExternalImageFormatPropertiesNV(3)

# VkExternalImageFormatPropertiesNV(3) Manual Page

## Name

VkExternalImageFormatPropertiesNV - Structure specifying external image format properties

## C Specification

The `VkExternalImageFormatPropertiesNV` structure is defined as:

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

## Members

- `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::`externalHandleType` can 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`
