## Name

VkScreenBufferPropertiesQNX - Properties of External Memory QNX Screen Buffers

Loading… please wait.

## C Specification

The `VkScreenBufferPropertiesQNX` structure returned is defined as:

    // Provided by VK_QNX_external_memory_screen_buffer
    typedef struct VkScreenBufferPropertiesQNX {
        VkStructureType    sType;
        void*              pNext;
        VkDeviceSize       allocationSize;
        uint32_t           memoryTypeBits;
    } VkScreenBufferPropertiesQNX;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `allocationSize` is the size of the external memory.

- `memoryTypeBits` is a bitmask containing one bit set for every memory type which the specified Screen buffer can be imported as.

## Description

Valid Usage (Implicit)

- VUID-VkScreenBufferPropertiesQNX-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_SCREEN_BUFFER_PROPERTIES_QNX`

- VUID-VkScreenBufferPropertiesQNX-pNext-pNext
  `pNext` must be `NULL` or a pointer to a valid instance of VkScreenBufferFormatPropertiesQNX

- VUID-VkScreenBufferPropertiesQNX-sType-unique
  The `sType` value of each struct in the `pNext` chain must be unique
