vkGetBufferDeviceAddress

To query a 64-bit buffer device address value which can be used to identify a buffer to API commands or through which buffer memory can be accessed, call:

VkDeviceAddress vkGetBufferDeviceAddress(
    VkDevice device,
    const VkBufferDeviceAddressInfo* pInfo);

pub fn get_buffer_device_address(
    device: vk::Device,
    p_info: *const vk::BufferDeviceAddressInfo,
) -> vk::DeviceAddress;

VkDeviceAddress vkGetBufferDeviceAddressKHR(
    VkDevice device,
    const VkBufferDeviceAddressInfo* pInfo);

pub fn get_buffer_device_address_khr(
    device: vk::Device,
    p_info: *const vk::BufferDeviceAddressInfo,
) -> vk::DeviceAddress;

VkDeviceAddress vkGetBufferDeviceAddressEXT(
    VkDevice device,
    const VkBufferDeviceAddressInfo* pInfo);

pub fn get_buffer_device_address_ext(
    device: vk::Device,
    p_info: *const vk::BufferDeviceAddressInfo,
) -> vk::DeviceAddress;

• device is the logical device that the buffer was created on.
• pInfo is a pointer to a VkBufferDeviceAddressInfo structure specifying the buffer to retrieve an address for.

The 64-bit return value, bufferBaseAddress, is an address of the start of pInfo→buffer. Addresses in the range [bufferBaseAddress, bufferBaseAddress + VkBufferCreateInfo::size) can be used to access the memory bound to this buffer on the device.

A value of zero is reserved as a null pointer and must not be returned as a valid buffer device address.

If the buffer was created with a non-zero value of VkBufferOpaqueCaptureAddressCreateInfo::opaqueCaptureAddress or VkBufferDeviceAddressCreateInfoEXT::deviceAddress, the return value will be the same address that was returned at capture time.

The returned address must satisfy the alignment requirement specified by VkMemoryRequirements::alignment for the buffer in VkBufferDeviceAddressInfo::buffer.

If multiple VkBuffer objects are bound to overlapping ranges of VkDeviceMemory, implementations may return address ranges which overlap. In this case, it is ambiguous which VkBuffer is associated with any given device address. For purposes of valid usage, if multiple VkBuffer objects can be attributed to a device address, a VkBuffer is selected such that valid usage passes, if it exists.
