Application hook functions could be declared as shown in the code below.It’s also up to a user to set the value of the pointers so that they point to the appropriate functions as shown below. The pointers do not have to be set in main() but, you can set them after calling OSInit().

void App_OS_TaskCreateHook (OS_TCB *p_tcb)

Note that not every hook function need to be defined, only the ones the user wants to place in the application code.
