C Specification
Alternatively, to
request a specific device address for a buffer, add a
VkBufferDeviceAddressCreateInfoEXT structure to the pNext
chain
of the VkBufferCreateInfo structure.
The VkBufferDeviceAddressCreateInfoEXT
structure is defined as:
// Provided by VK_EXT_buffer_device_address
typedef struct VkBufferDeviceAddressCreateInfoEXT {
VkStructureType sType;
const void* pNext;
VkDeviceAddress deviceAddress;
} VkBufferDeviceAddressCreateInfoEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
deviceAddress
is the device address requested for the buffer.
Description
If deviceAddress
is zero, no specific address is requested.
If deviceAddress
is not zero, then it must be an address retrieved
from an identically created buffer on the same implementation.
The buffer must also be bound to an identically created
VkDeviceMemory
object.
If this structure is not present, it is as if deviceAddress
is zero.
Apps should avoid creating buffers with app-provided addresses and
implementation-provided addresses in the same process, to reduce the
likelihood of VK_ERROR_INVALID_DEVICE_ADDRESS_EXT
errors.
