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:

typedef struct VkImportAndroidHardwareBufferInfoANDROID {
    VkStructureType            sType;
    const void*                pNext;
    struct AHardwareBuffer*    buffer;
} VkImportAndroidHardwareBufferInfoANDROID;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific 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)
  • sType must be VK_STRUCTURE_TYPE_IMPORT_ANDROID_HARDWARE_BUFFER_INFO_ANDROID

  • buffer must be a valid pointer to an AHardwareBuffer value
