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;


  • 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.


The number of command buffers allocated using commandBufferCount counts against the maximum number of command buffers reserved via VkCommandPoolMemoryReservationCreateInfo::commandPoolMaxCommandBuffers specified when commandPool was created. Once command buffers are freed with vkFreeCommandBuffers, they can be allocated from commandPool again.

Valid Usage
  • VUID-VkCommandBufferAllocateInfo-commandPool-05006
    The number of command buffers currently allocated from commandPool plus commandBufferCount must be less than or equal to the value of VkCommandPoolMemoryReservationCreateInfo::commandPoolMaxCommandBuffers specified when commandPool was created

Valid Usage (Implicit)
  • VUID-VkCommandBufferAllocateInfo-sType-sType

  • 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
