C Specification

The VkDescriptorSetAllocateInfo structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkDescriptorSetAllocateInfo {
    VkStructureType                 sType;
    const void*                     pNext;
    VkDescriptorPool                descriptorPool;
    uint32_t                        descriptorSetCount;
    const VkDescriptorSetLayout*    pSetLayouts;
} VkDescriptorSetAllocateInfo;


  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • descriptorPool is the pool which the sets will be allocated from.

  • descriptorSetCount determines the number of descriptor sets to be allocated from the pool.

  • pSetLayouts is a pointer to an array of descriptor set layouts, with each member specifying how the corresponding descriptor set is allocated.


Valid Usage
  • VUID-VkDescriptorSetAllocateInfo-pSetLayouts-03044
    If any element of pSetLayouts was created with the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set, descriptorPool must have been created with the VK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT flag set

  • VUID-VkDescriptorSetAllocateInfo-pSetLayouts-09380
    If pSetLayouts[i] was created with an element of pBindingFlags that includes VK_DESCRIPTOR_BINDING_VARIABLE_DESCRIPTOR_COUNT_BIT, and VkDescriptorSetVariableDescriptorCountAllocateInfo is included in the pNext chain, and VkDescriptorSetVariableDescriptorCountAllocateInfo::descriptorSetCount is not zero, then VkDescriptorSetVariableDescriptorCountAllocateInfo::pDescriptorCounts[i] must be less than or equal to VkDescriptorSetLayoutBinding::descriptorCount for the corresponding binding used to create pSetLayouts[i]

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

  • VUID-VkDescriptorSetAllocateInfo-pNext-pNext
    pNext must be NULL or a pointer to a valid instance of VkDescriptorSetVariableDescriptorCountAllocateInfo

  • VUID-VkDescriptorSetAllocateInfo-sType-unique
    The sType value of each struct in the pNext chain must be unique

  • VUID-VkDescriptorSetAllocateInfo-descriptorPool-parameter
    descriptorPool must be a valid VkDescriptorPool handle

  • VUID-VkDescriptorSetAllocateInfo-pSetLayouts-parameter
    pSetLayouts must be a valid pointer to an array of descriptorSetCount valid VkDescriptorSetLayout handles

  • VUID-VkDescriptorSetAllocateInfo-descriptorSetCount-arraylength
    descriptorSetCount must be greater than 0

  • VUID-VkDescriptorSetAllocateInfo-commonparent
    Both of descriptorPool, and the elements of pSetLayouts must have been created, allocated, or retrieved from the same VkDevice
