# VkDevicePrivateDataCreateInfo(3) Manual Page

## Name

VkDevicePrivateDataCreateInfo - Reserve private data slots

Loading… please wait.

## C Specification

To reserve private data storage slots, add a VkDevicePrivateDataCreateInfo structure to the `pNext` chain of the VkDeviceCreateInfo structure. Reserving slots in this manner is not strictly necessary, but doing so may improve performance.

    // Provided by VK_VERSION_1_3
    typedef struct VkDevicePrivateDataCreateInfo {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           privateDataSlotRequestCount;
    } VkDevicePrivateDataCreateInfo;

or the equivalent

    // Provided by VK_EXT_private_data
    typedef VkDevicePrivateDataCreateInfo VkDevicePrivateDataCreateInfoEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

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

- `privateDataSlotRequestCount` is the amount of slots to reserve.

## Description

Valid Usage (Implicit)

- VUID-VkDevicePrivateDataCreateInfo-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_DEVICE_PRIVATE_DATA_CREATE_INFO`
