C Specification
To request a specific device address for a memory allocation, add a
VkMemoryOpaqueCaptureAddressAllocateInfoKHR structure to the
pNext
chain of the VkMemoryAllocateInfo structure.
The VkMemoryOpaqueCaptureAddressAllocateInfoKHR
structure is defined
as:
typedef struct VkMemoryOpaqueCaptureAddressAllocateInfoKHR {
VkStructureType sType;
const void* pNext;
uint64_t opaqueCaptureAddress;
} VkMemoryOpaqueCaptureAddressAllocateInfoKHR;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to an extension-specific structure. -
opaqueCaptureAddress
is 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 vkGetDeviceMemoryOpaqueCaptureAddressKHR 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.
