# VkPhysicalDevicePushDescriptorProperties(3) Manual Page

## Name

VkPhysicalDevicePushDescriptorProperties - Structure describing push descriptor limits that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDevicePushDescriptorProperties` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkPhysicalDevicePushDescriptorProperties {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxPushDescriptors;
    } VkPhysicalDevicePushDescriptorProperties;

or the equivalent

    // Provided by VK_KHR_push_descriptor
    typedef VkPhysicalDevicePushDescriptorProperties VkPhysicalDevicePushDescriptorPropertiesKHR;

## Members

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

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

## Description

- `maxPushDescriptors` is the maximum number of descriptors that can be used in a descriptor set layout created with `VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT` set.

If the `VkPhysicalDevicePushDescriptorProperties` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDevicePushDescriptorProperties-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PUSH_DESCRIPTOR_PROPERTIES`
