C Specification

To determine the memory requirements for a buffer resource, call:

// Provided by VK_VERSION_1_1
void vkGetBufferMemoryRequirements2(
    VkDevice                                    device,
    const VkBufferMemoryRequirementsInfo2*      pInfo,
    VkMemoryRequirements2*                      pMemoryRequirements);


  • device is the logical device that owns the buffer.

  • pInfo is a pointer to a VkBufferMemoryRequirementsInfo2 structure containing parameters required for the memory requirements query.

  • pMemoryRequirements is a pointer to a VkMemoryRequirements2 structure in which the memory requirements of the buffer object are returned.


Valid Usage (Implicit)
  • VUID-vkGetBufferMemoryRequirements2-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetBufferMemoryRequirements2-pInfo-parameter
    pInfo must be a valid pointer to a valid VkBufferMemoryRequirementsInfo2 structure

  • VUID-vkGetBufferMemoryRequirements2-pMemoryRequirements-parameter
    pMemoryRequirements must be a valid pointer to a VkMemoryRequirements2 structure
