## Name

VkDrmFormatModifierPropertiesListEXT - Structure specifying the list of DRM format modifiers supported for a format

Loading… please wait.

## C Specification

To obtain the list of Linux DRM format modifiers compatible with a VkFormat, add a VkDrmFormatModifierPropertiesListEXT structure to the `pNext` chain of VkFormatProperties2.

The VkDrmFormatModifierPropertiesListEXT structure is defined as:

    // Provided by VK_EXT_image_drm_format_modifier
    typedef struct VkDrmFormatModifierPropertiesListEXT {
        VkStructureType                      sType;
        void*                                pNext;
        uint32_t                             drmFormatModifierCount;
        VkDrmFormatModifierPropertiesEXT*    pDrmFormatModifierProperties;
    } VkDrmFormatModifierPropertiesListEXT;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `drmFormatModifierCount` is an inout parameter related to the number of modifiers compatible with the `format`, as described below.

- `pDrmFormatModifierProperties` is either `NULL` or a pointer to an array of VkDrmFormatModifierPropertiesEXT structures.

## Description

If `pDrmFormatModifierProperties` is `NULL`, then the function returns in `drmFormatModifierCount` the number of modifiers compatible with the queried `format`. Otherwise, the application must set `drmFormatModifierCount` to the length of the array `pDrmFormatModifierProperties`; the function will write at most `drmFormatModifierCount` elements to the array, and will return in `drmFormatModifierCount` the number of elements written.

Among the elements in array `pDrmFormatModifierProperties`, each returned `drmFormatModifier` must be unique.

Valid Usage (Implicit)

- VUID-VkDrmFormatModifierPropertiesListEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_DRM_FORMAT_MODIFIER_PROPERTIES_LIST_EXT`
