** Source: test1.c
**
** Purpose: Tests that FlushInstructionCache returns the correct value for a
** number of different inputs.
**
**
** Note :
** For this function, what constitutes "invalid parameters" will depend entirely
** on the platform; because of this we can't simply test values on Windows and
** then ask for the same results everywhere. Because of this, this test can
** ensure that the function succeeds for some "obviously" valid values, but
** can't make sure that it fails for invalid values.
