# VkPhysicalDeviceNestedCommandBufferPropertiesEXT(3) Manual Page

## Name

VkPhysicalDeviceNestedCommandBufferPropertiesEXT - Structure describing the nested command buffer limits of an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceNestedCommandBufferPropertiesEXT` structure is defined as:

    // Provided by VK_EXT_nested_command_buffer
    typedef struct VkPhysicalDeviceNestedCommandBufferPropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxCommandBufferNestingLevel;
    } VkPhysicalDeviceNestedCommandBufferPropertiesEXT;

## Members

The members of the `VkPhysicalDeviceNestedCommandBufferPropertiesEXT` structure describe the following features:

## Description

- `maxCommandBufferNestingLevel` indicates the maximum nesting level of calls to vkCmdExecuteCommands from Secondary Command Buffers. A `maxCommandBufferNestingLevel` of `UINT32_MAX` means there is no limit to the nesting level.

If the `VkPhysicalDeviceNestedCommandBufferPropertiesEXT` 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-VkPhysicalDeviceNestedCommandBufferPropertiesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_NESTED_COMMAND_BUFFER_PROPERTIES_EXT`
