Routine Description:
This routine dumps LDT selectors. The selectors are dumped from the
user mode Ldt, rather than the system ldt.
Arguments:
CurrentProcess -- Supplies a handle to the process to dump selectors for
CurrentThread -- Supplies a handle to the thread to dump selectors for
ArgumentString -- Supplies the arguments to the !sel command
Return Value
None.
