vkGetDeviceMemoryOpaqueCaptureAddress
To query a 64-bit opaque capture address value from a memory object, call:
uint64_t vkGetDeviceMemoryOpaqueCaptureAddressKHR(
VkDevice device,
const VkDeviceMemoryOpaqueCaptureAddressInfo* pInfo);
device
is the logical device that the memory object was allocated on.pInfo
is a pointer to a VkDeviceMemoryOpaqueCaptureAddressInfo structure specifying the memory object to retrieve an address for.
The 64-bit return value is an opaque address representing the start of
pInfo→memory
.
If the memory object was allocated with a non-zero value of
VkMemoryOpaqueCaptureAddressAllocateInfo::opaqueCaptureAddress
,
the return value must be the same address.
The expected usage for these opaque addresses is only for trace capture/replay tools to store these addresses in a trace and subsequently specify them during replay.
Valid Usage
VUID-vkGetDeviceMemoryOpaqueCaptureAddress-None-03334
The bufferDeviceAddress
feature
must be enabled
VUID-vkGetDeviceMemoryOpaqueCaptureAddress-device-03335
If device
was created with multiple physical devices, then the
bufferDeviceAddressMultiDevice
feature must be enabled
Valid Usage (Implicit)
VUID-vkGetDeviceMemoryOpaqueCaptureAddress-device-parameter
device
must be a valid VkDevice handle
VUID-vkGetDeviceMemoryOpaqueCaptureAddress-pInfo-parameter
pInfo
must be a valid pointer to a valid VkDeviceMemoryOpaqueCaptureAddressInfo structure
