C Specification
To request a specific device address for a memory allocation, add a
VkMemoryOpaqueCaptureAddressAllocateInfo structure to the pNext
chain of the VkMemoryAllocateInfo structure.
The VkMemoryOpaqueCaptureAddressAllocateInfo structure is defined as:
// Provided by VK_VERSION_1_2
typedef struct VkMemoryOpaqueCaptureAddressAllocateInfo {
VkStructureType sType;
const void* pNext;
uint64_t opaqueCaptureAddress;
} VkMemoryOpaqueCaptureAddressAllocateInfo;
or the equivalent
// Provided by VK_KHR_buffer_device_address
typedef VkMemoryOpaqueCaptureAddressAllocateInfo VkMemoryOpaqueCaptureAddressAllocateInfoKHR;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
opaqueCaptureAddressis the opaque capture address requested for the memory allocation.
Description
If opaqueCaptureAddress is zero, no specific address is requested.
If opaqueCaptureAddress is not zero, it should be an address
retrieved from vkGetDeviceMemoryOpaqueCaptureAddress on an identically
created memory allocation on the same implementation.

Note
|
In most cases, it is expected that a non-zero This is, however, not a strict requirement because trace capture/replay tools may need to adjust memory allocation parameters for imported memory. |
If this structure is not present, it is as if opaqueCaptureAddress is
zero.
