VkBufferDeviceAddressCreateInfoEXT

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:

typedef struct VkBufferDeviceAddressCreateInfoEXT {
    VkStructureType sType;
    const void* pNext;
    VkDeviceAddress deviceAddress;
} VkBufferDeviceAddressCreateInfoEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• deviceAddress is the device address requested for the buffer.

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.
