## Description

This function displays function call trace information.

When you are using a thread system, it will display the information for a specified thread. In the case of NULL, it will be the current thread. It will not display if you are not using a thread system. In that case, use `OS_DumpCallTrace()`.

The display meanings are the same as those for `OS_DumpCallTrace()`. Refer to the function description for more information.

If this function is compiled for debugging, it will function properly. However, if compiled for the final ROM version (`FINALROM`) library, it will not do anything.
