C Specification
The VkWriteDescriptorSet structure is defined as:
// Provided by VK_VERSION_1_0
typedef struct VkWriteDescriptorSet {
VkStructureType sType;
const void* pNext;
VkDescriptorSet dstSet;
uint32_t dstBinding;
uint32_t dstArrayElement;
uint32_t descriptorCount;
VkDescriptorType descriptorType;
const VkDescriptorImageInfo* pImageInfo;
const VkDescriptorBufferInfo* pBufferInfo;
const VkBufferView* pTexelBufferView;
} VkWriteDescriptorSet;Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
dstSetis the destination descriptor set to update. -
dstBindingis the descriptor binding within that set. -
dstArrayElementis the starting element in that array. -
descriptorCountis the number of descriptors to update.descriptorCountis one of-

descriptorTypeis a VkDescriptorType specifying the type of each descriptor inpImageInfo,pBufferInfo, orpTexelBufferView, as described below. It must be the same type as thedescriptorTypespecified inVkDescriptorSetLayoutBindingfordstSetatdstBinding. The type of the descriptor also controls which array the descriptors are taken from. -
pImageInfois a pointer to an array of VkDescriptorImageInfo structures or is ignored, as described below. -
pBufferInfois a pointer to an array of VkDescriptorBufferInfo structures or is ignored, as described below. -
pTexelBufferViewis a pointer to an array of VkBufferView handles as described in the Buffer Views section or is ignored, as described below.
Description
Only one of pImageInfo, pBufferInfo, or pTexelBufferView
members is used according to the descriptor type specified in the
descriptorType member of the containing VkWriteDescriptorSet
structure,
as specified below.
If the nullDescriptor feature is enabled,
the buffer,
imageView, or bufferView can be VK_NULL_HANDLE.
Loads from a null descriptor return zero values and stores and atomics to a
null descriptor are discarded.
If the dstBinding has fewer than descriptorCount array elements
remaining starting from dstArrayElement, then the remainder will be
used to update the subsequent binding - dstBinding+1 starting at
array element zero.
If a binding has a descriptorCount of zero, it is skipped.
This behavior applies recursively, with the update affecting consecutive
bindings as needed to update all descriptorCount descriptors.
Consecutive bindings must have identical VkDescriptorType,
VkShaderStageFlags,
VkDescriptorBindingFlagBits,
and immutable samplers references.
