vkSubmitDebugUtilsMessageEXT

To intentionally submit a debug message, call:

void vkSubmitDebugUtilsMessageEXT(
    VkInstance instance,
    VkDebugUtilsMessageSeverityFlagBitsEXT messageSeverity,
    VkDebugUtilsMessageTypeFlagsEXT messageTypes,
    const VkDebugUtilsMessengerCallbackDataEXT* pCallbackData);

• instance is the debug stream’s VkInstance.
• messageSeverity is a VkDebugUtilsMessageSeverityFlagBitsEXT value specifying the severity of this event/message.
• messageTypes is a bitmask of VkDebugUtilsMessageTypeFlagBitsEXT specifying which type of event(s) to identify with this message.
• pCallbackData contains all the callback related data in the VkDebugUtilsMessengerCallbackDataEXT structure.

The call will propagate through the layers and generate callback(s) as indicated by the message’s flags. The parameters are passed on to the callback in addition to the pUserData value that was defined at the time the messenger was registered.
