C Specification
The prototype for the
VkDebugUtilsMessengerCreateInfoEXT::pfnUserCallback function
implemented by the application is:
// Provided by VK_EXT_debug_utils
typedef VkBool32 (VKAPI_PTR *PFN_vkDebugUtilsMessengerCallbackEXT)(
VkDebugUtilsMessageSeverityFlagBitsEXT messageSeverity,
VkDebugUtilsMessageTypeFlagsEXT messageTypes,
const VkDebugUtilsMessengerCallbackDataEXT* pCallbackData,
void* pUserData);
Parameters
-
messageSeverityspecifies the VkDebugUtilsMessageSeverityFlagBitsEXT that triggered this callback. -
messageTypesis a bitmask of VkDebugUtilsMessageTypeFlagBitsEXT specifying which type of event(s) triggered this callback. -
pCallbackDatacontains all the callback related data in the VkDebugUtilsMessengerCallbackDataEXT structure. -
pUserDatais the user data provided when the VkDebugUtilsMessengerEXT was created.
Description
The callback returns a VkBool32, which is interpreted in a
layer-specified manner.
The application should always return VK_FALSE.
The VK_TRUE value is reserved for use in layer development.
