Problems with user-extension

[Jan Suchotzki]

Hi,

I would like to register a task_create_extension at the system 
wide, statical extension-table.

I defined the following:

rtems_extension TaskCreate (
  rtems_tcb *current_task,
  rtems_tcb *new_task
) {
...
}

rtems_extensions_table Extensions = {
  TaskCreate,                      /* task create user extension */
...
};

I got the following error from the compiler:

 initialization to `boolean (*)(Thread_Control *, Thread_Control 
*)' from `rtems_extension (*)(rtems_tcb *, rtems_tcb *)'


I found at userext.h that the task_create_extension has another 
definition compared to all other extensions. But how to fix the 
problem???

With kind regards...
...Jan
