## Name

vkCreateDebugReportCallbackEXT - Create a debug report callback object

Loading… please wait.

## C Specification

Debug report callbacks give more detailed feedback on the application’s use of Vulkan when events of interest occur.

To register a debug report callback, an application uses vkCreateDebugReportCallbackEXT.

    // Provided by VK_EXT_debug_report
    VkResult vkCreateDebugReportCallbackEXT(
        VkInstance                                  instance,
        const VkDebugReportCallbackCreateInfoEXT*   pCreateInfo,
        const VkAllocationCallbacks*                pAllocator,
        VkDebugReportCallbackEXT*                   pCallback);

## Parameters

- `instance` is the instance the callback will be logged on.

- `pCreateInfo` is a pointer to a VkDebugReportCallbackCreateInfoEXT structure defining the conditions under which this callback will be called.

- `pAllocator` controls host memory allocation as described in the Memory Allocation chapter.

- `pCallback` is a pointer to a VkDebugReportCallbackEXT handle in which the created object is returned.

## Description

Valid Usage (Implicit)

- `instance` must be a valid VkInstance handle

- `pCreateInfo` must be a valid pointer to a valid VkDebugReportCallbackCreateInfoEXT structure

- If `pAllocator` is not `NULL`, `pAllocator` must be a valid pointer to a valid VkAllocationCallbacks structure

- `pCallback` must be a valid pointer to a VkDebugReportCallbackEXT handle

Return Codes

On success, this command returns

  - `VK_SUCCESS`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`
