VkImportAndroidHardwareBufferInfoANDROID(3)

Name

VkImportAndroidHardwareBufferInfoANDROID - Import memory from an Android hardware buffer

C Specification

To import memory created outside of the current Vulkan instance from an Android hardware buffer, add a VkImportAndroidHardwareBufferInfoANDROID structure to the pNext chain of the VkMemoryAllocateInfo structure. The VkImportAndroidHardwareBufferInfoANDROID structure is defined as:

// Provided by VK_ANDROID_external_memory_android_hardware_buffer
typedef struct VkImportAndroidHardwareBufferInfoANDROID {
    VkStructureType            sType;
    const void*                pNext;
    struct AHardwareBuffer*    buffer;
} VkImportAndroidHardwareBufferInfoANDROID;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • buffer is the Android hardware buffer to import.

Description

If the vkAllocateMemory command succeeds, the implementation must acquire a reference to the imported hardware buffer, which it must release when the device memory object is freed. If the command fails, the implementation must not retain a reference.

Valid Usage
Valid Usage (Implicit)

  • VUID-VkImportAndroidHardwareBufferInfoANDROID-sType-sType
    sType must be VK_STRUCTURE_TYPE_IMPORT_ANDROID_HARDWARE_BUFFER_INFO_ANDROID

  • VUID-VkImportAndroidHardwareBufferInfoANDROID-buffer-parameter
    buffer must be a valid pointer to an AHardwareBuffer value
