C Specification

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

// Provided by VK_VERSION_1_0
void vkGetBufferMemoryRequirements(
    VkDevice                                    device,
    VkBuffer                                    buffer,
    VkMemoryRequirements*                       pMemoryRequirements);


  • device is the logical device that owns the buffer.

  • buffer is the buffer to query.

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


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

  • VUID-vkGetBufferMemoryRequirements-buffer-parameter
    buffer must be a valid VkBuffer handle

  • VUID-vkGetBufferMemoryRequirements-pMemoryRequirements-parameter
    pMemoryRequirements must be a valid pointer to a VkMemoryRequirements structure

  • VUID-vkGetBufferMemoryRequirements-buffer-parent
    buffer must have been created, allocated, or retrieved from device
