## Name

VkCommandBufferAllocateInfo - Structure specifying the allocation parameters for command buffer object

Loading… please wait.

## C Specification

The `VkCommandBufferAllocateInfo` structure is defined as:

    // Provided by VK_VERSION_1_0
    typedef struct VkCommandBufferAllocateInfo {
        VkStructureType         sType;
        const void*             pNext;
        VkCommandPool           commandPool;
        VkCommandBufferLevel    level;
        uint32_t                commandBufferCount;
    } VkCommandBufferAllocateInfo;

## Members

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

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

- `commandPool` is the command pool from which the command buffers are allocated.

- `level` is a VkCommandBufferLevel value specifying the command buffer level.

- `commandBufferCount` is the number of command buffers to allocate from the pool.

## Description

Valid Usage (Implicit)

- VUID-VkCommandBufferAllocateInfo-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_COMMAND_BUFFER_ALLOCATE_INFO

- VUID-VkCommandBufferAllocateInfo-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkCommandBufferAllocateInfo-commandPool-parameter
  `commandPool` must be a valid VkCommandPool handle

- VUID-VkCommandBufferAllocateInfo-level-parameter
  `level` must be a valid VkCommandBufferLevel value

Host Synchronization

- Host access to `commandPool` must be externally synchronized
