C Specification
A debug messenger triggers a debug callback with a debug message when an event of interest occurs. To create a debug messenger which will trigger a debug callback, call:
// Provided by VK_EXT_debug_utils
VkResult vkCreateDebugUtilsMessengerEXT(
VkInstance instance,
const VkDebugUtilsMessengerCreateInfoEXT* pCreateInfo,
const VkAllocationCallbacks* pAllocator,
VkDebugUtilsMessengerEXT* pMessenger);
Parameters
-
instance
is the instance the messenger will be used with. -
pCreateInfo
is a pointer to a VkDebugUtilsMessengerCreateInfoEXT structure containing the callback pointer, as well as defining conditions under which this messenger will trigger the callback. -
pAllocator
controls host memory allocation as described in the Memory Allocation chapter. -
pMessenger
is a pointer to a VkDebugUtilsMessengerEXT handle in which the created object is returned.
Description
The application must ensure that vkCreateDebugUtilsMessengerEXT is
not executed in parallel with any Vulkan command that is also called with
instance
or child of instance
as the dispatchable argument.
