C Specification

The VkCopyBufferInfo2 structure is defined as:

// Provided by VK_VERSION_1_3
typedef struct VkCopyBufferInfo2 {
    VkStructureType         sType;
    const void*             pNext;
    VkBuffer                srcBuffer;
    VkBuffer                dstBuffer;
    uint32_t                regionCount;
    const VkBufferCopy2*    pRegions;
} VkCopyBufferInfo2;

or the equivalent

// Provided by VK_KHR_copy_commands2
typedef VkCopyBufferInfo2 VkCopyBufferInfo2KHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • srcBuffer is the source buffer.

  • dstBuffer is the destination buffer.

  • regionCount is the number of regions to copy.

  • pRegions is a pointer to an array of VkBufferCopy2 structures specifying the regions to copy.

Description

Valid Usage

  • VUID-VkCopyBufferInfo2-srcOffset-00113
    The srcOffset member of each element of pRegions must be less than the size of srcBuffer

  • VUID-VkCopyBufferInfo2-dstOffset-00114
    The dstOffset member of each element of pRegions must be less than the size of dstBuffer

  • VUID-VkCopyBufferInfo2-size-00115
    The size member of each element of pRegions must be less than or equal to the size of srcBuffer minus srcOffset

  • VUID-VkCopyBufferInfo2-size-00116
    The size member of each element of pRegions must be less than or equal to the size of dstBuffer minus dstOffset

  • VUID-VkCopyBufferInfo2-pRegions-00117
    The union of the source regions, and the union of the destination regions, specified by the elements of pRegions, must not overlap in memory

  • VUID-VkCopyBufferInfo2-srcBuffer-00118
    srcBuffer must have been created with VK_BUFFER_USAGE_TRANSFER_SRC_BIT usage flag

  • VUID-VkCopyBufferInfo2-srcBuffer-00119
    If srcBuffer is non-sparse then it must be bound completely and contiguously to a single VkDeviceMemory object

  • VUID-VkCopyBufferInfo2-dstBuffer-00120
    dstBuffer must have been created with VK_BUFFER_USAGE_TRANSFER_DST_BIT usage flag

  • VUID-VkCopyBufferInfo2-dstBuffer-00121
    If dstBuffer is non-sparse then it must be bound completely and contiguously to a single VkDeviceMemory object

Valid Usage (Implicit)

  • VUID-VkCopyBufferInfo2-sType-sType
    sType must be VK_STRUCTURE_TYPE_COPY_BUFFER_INFO_2

  • VUID-VkCopyBufferInfo2-pNext-pNext
    pNext must be NULL

  • VUID-VkCopyBufferInfo2-srcBuffer-parameter
    srcBuffer must be a valid VkBuffer handle

  • VUID-VkCopyBufferInfo2-dstBuffer-parameter
    dstBuffer must be a valid VkBuffer handle

  • VUID-VkCopyBufferInfo2-pRegions-parameter
    pRegions must be a valid pointer to an array of regionCount valid VkBufferCopy2 structures

  • VUID-VkCopyBufferInfo2-regionCount-arraylength
    regionCount must be greater than 0

  • VUID-VkCopyBufferInfo2-commonparent
    Both of dstBuffer, and srcBuffer must have been created, allocated, or retrieved from the same VkDevice
