C Specification
To import memory created outside of the current Vulkan instance from a QNX
Screen buffer, add a VkImportScreenBufferInfoQNX
structure to the
pNext
chain of the VkMemoryAllocateInfo structure.
The VkImportScreenBufferInfoQNX
structure is defined as:
// Provided by VK_QNX_external_memory_screen_buffer
typedef struct VkImportScreenBufferInfoQNX {
VkStructureType sType;
const void* pNext;
struct _screen_buffer* buffer;
} VkImportScreenBufferInfoQNX;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
buffer
is a pointer to astruct
_screen_buffer
, the QNX Screen buffer to import
Description
The implementation may not acquire a reference to the imported Screen
buffer.
Therefore, the application must ensure that the object referred to by
buffer
stays valid as long as the device memory to which it is
imported is being used.
