C Specification
To query the memory size needed to copy to or from an image using
vkCopyMemoryToImage or vkCopyImageToMemory when the
VK_HOST_IMAGE_COPY_MEMCPY
flag is specified, add a
VkSubresourceHostMemcpySize structure to the pNext
chain of the
VkSubresourceLayout2 structure in a call to
vkGetImageSubresourceLayout2.
The VkSubresourceHostMemcpySize
structure is defined as:
// Provided by VK_VERSION_1_4
typedef struct VkSubresourceHostMemcpySize {
VkStructureType sType;
void* pNext;
VkDeviceSize size;
} VkSubresourceHostMemcpySize;
or the equivalent
// Provided by VK_EXT_host_image_copy
typedef VkSubresourceHostMemcpySize VkSubresourceHostMemcpySizeEXT;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
size
is the size in bytes of the image subresource.
