C Specification
The VkDescriptorUpdateTemplateEntry structure is defined as:
typedef struct VkDescriptorUpdateTemplateEntry {
uint32_t dstBinding;
uint32_t dstArrayElement;
uint32_t descriptorCount;
VkDescriptorType descriptorType;
size_t offset;
size_t stride;
} VkDescriptorUpdateTemplateEntry;
or the equivalent
typedef VkDescriptorUpdateTemplateEntry VkDescriptorUpdateTemplateEntryKHR;
Members
-
dstBindingis the descriptor binding to update when using this descriptor update template. -
dstArrayElementis the starting element in the array belonging todstBinding. If the descriptor binding identified bysrcBindinghas a descriptor type ofVK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK_EXTthendstArrayElementspecifies the starting byte offset to update. -
descriptorCountis the number of descriptors to update. IfdescriptorCountis greater than the number of remaining array elements in the destination binding, those affect consecutive bindings in a manner similar to VkWriteDescriptorSet above. If the descriptor binding identified bydstBindinghas a descriptor type ofVK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK_EXTthendescriptorCountspecifies the number of bytes to update and the remaining array elements in the destination binding refer to the remaining number of bytes in it. -
descriptorTypeis a VkDescriptorType specifying the type of the descriptor. -
offsetis the offset in bytes of the first binding in the raw data structure. -
strideis the stride in bytes between two consecutive array elements of the descriptor update informations in the raw data structure. The actual pointer ptr for each array element j of update entry i is computed using the following formula:const char *ptr = (const char *)pData + pDescriptorUpdateEntries[i].offset + j * pDescriptorUpdateEntries[i].strideThe stride is useful in case the bindings are stored in structs along with other data. If
descriptorTypeisVK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK_EXTthen the value ofstrideis ignored and the stride is assumed to be1, i.e. the descriptor update information for them is always specified as a contiguous range.
