/**
 * Application-defined debug report callback function.
 * 
 * C Specification
 * 
 * The prototype for the {@link VkDebugReportCallbackCreateInfoEXT}{@code ::pfnCallback} function implemented by the application is:
 * 
 *  * typedef VkBool32 (VKAPI_PTR *PFN_vkDebugReportCallbackEXT)(
 *     VkDebugReportFlagsEXT                       flags,
 *     VkDebugReportObjectTypeEXT                  objectType,
 *     uint64_t                                    object,
 *     size_t                                      location,
 *     int32_t                                     messageCode,
 *     const char*                                 pLayerPrefix,
 *     const char*                                 pMessage,
 *     void*                                       pUserData);
 * 
 * Description
 * 
 * The callback must not call {@link EXTDebugReport#vkDestroyDebugReportCallbackEXT DestroyDebugReportCallbackEXT}.
 * 
 * The callback returns a {@code VkBool32}, which is interpreted in a layer-specified manner. The application should always return {@link VK10#VK_FALSE FALSE}. The {@link VK10#VK_TRUE TRUE} value is reserved for use in layer development.
 * 
 * Valid Usage
 * 
 * 
 * {@code object} must be a Vulkan object or {@link VK10#VK_NULL_HANDLE NULL_HANDLE}.
 * If {@code objectType} is not {@link EXTDebugReport#VK_DEBUG_REPORT_OBJECT_TYPE_UNKNOWN_EXT DEBUG_REPORT_OBJECT_TYPE_UNKNOWN_EXT} and {@code object} is not {@link VK10#VK_NULL_HANDLE NULL_HANDLE}, {@code object} must be a Vulkan object of the corresponding type associated with {@code objectType} as defined in the “{@code VkDebugReportObjectTypeEXT} and Vulkan Handle Relationship” table.
 * 
 * 
 * See Also
 * 
 * {@link VkDebugReportCallbackCreateInfoEXT}
