# VkDebugReportFlagBitsEXT(3) Manual Page

## Name

VkDebugReportFlagBitsEXT - Bitmask specifying events which cause a debug report callback

Loading… please wait.

## C Specification

Bits which can be set in VkDebugReportCallbackCreateInfoEXT::`flags`, specifying events which cause a debug report, are:

    // Provided by VK_EXT_debug_report
    typedef enum VkDebugReportFlagBitsEXT {
        VK_DEBUG_REPORT_INFORMATION_BIT_EXT = 0x00000001,
        VK_DEBUG_REPORT_WARNING_BIT_EXT = 0x00000002,
        VK_DEBUG_REPORT_PERFORMANCE_WARNING_BIT_EXT = 0x00000004,
        VK_DEBUG_REPORT_ERROR_BIT_EXT = 0x00000008,
        VK_DEBUG_REPORT_DEBUG_BIT_EXT = 0x00000010,
    } VkDebugReportFlagBitsEXT;

## Description

- `VK_DEBUG_REPORT_ERROR_BIT_EXT` specifies that the application has violated a valid usage condition of the specification.

- `VK_DEBUG_REPORT_WARNING_BIT_EXT` specifies use of Vulkan that may expose an application bug. Such cases may not be immediately harmful, such as a fragment shader outputting to a location with no attachment. Other cases may point to behavior that is almost certainly bad when unintended such as using an image whose memory has not been filled. In general if you see a warning but you know that the behavior is intended/desired, then simply ignore the warning.

- `VK_DEBUG_REPORT_PERFORMANCE_WARNING_BIT_EXT` specifies a potentially non-optimal use of Vulkan, e.g. using vkCmdClearColorImage when setting VkAttachmentDescription::`loadOp` to `VK_ATTACHMENT_LOAD_OP_CLEAR` would have worked.

- `VK_DEBUG_REPORT_INFORMATION_BIT_EXT` specifies an informational message such as resource details that may be handy when debugging an application.

- `VK_DEBUG_REPORT_DEBUG_BIT_EXT` specifies diagnostic information from the implementation and layers.
