If a window has either the WS_CLIPCHILDREN or WS_CLIPSIBLINGS style, a slight loss in performance occurs. Each window takes up system resources, so an application should not use child windows indiscriminately. For best performance, an application that needs to logically divide its main window ...

Heap3 scheme only wraps the standard C library malloc() and free() functions to provide thread safety. In this case, when you use pvPortMalloc(), the function will use malloc() to allocate memory. It's not like vPortFree() isn't working. It is, but you will n...
