Loading… please wait.

## C Specification

Possible values of VkDeviceMemoryReportCallbackDataEXT::`type`, specifying event types which cause the device driver to call the callback, are:

    // Provided by VK_EXT_device_memory_report
    typedef enum VkDeviceMemoryReportEventTypeEXT {
        VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATE_EXT = 0,
        VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_FREE_EXT = 1,
        VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_IMPORT_EXT = 2,
        VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_UNIMPORT_EXT = 3,
        VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATION_FAILED_EXT = 4,
    } VkDeviceMemoryReportEventTypeEXT;

## Description

- `VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATE_EXT` specifies this event corresponds to the allocation of an internal device memory object or a VkDeviceMemory.

- `VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_FREE_EXT` specifies this event corresponds to the deallocation of an internally-allocated device memory object or a VkDeviceMemory.

- `VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_IMPORT_EXT` specifies this event corresponds to the import of an external memory object.

- `VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_UNIMPORT_EXT` specifies this event is the release of an imported external memory object.

- `VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATION_FAILED_EXT` specifies this event corresponds to the failed allocation of an internal device memory object or a VkDeviceMemory.
