Routine Description:

    Calls the debugger to reload symbols.

Arguments:

                 /u  unload symbols, no reload

        A value of NULL is equivalent to an empty string

Routine Description:

    Calls the debugger to set or retrieve symbol search path.

Arguments:

    Arg - Supplies new search path.  If Arg is NULL or string is empty,
            the search path is not changed and the current setting is
            returned in Result.  When the symbol search path is changed,
            a call to ReloadSymbols is made implicitly.

    Result - OPTIONAL Returns the symbol search path setting.

    Length - Supplies the size of the buffer supplied by Result.

Return Value:
