*
*   Test of the C wrapper for the DateTimePatternGenerator.
*   Calls each C API function and exercises code paths in the wrapper,
*   but the full functionality is tested in the C++ intltest.
*
*   One item to note: C API functions which return a const UChar *
*   should return a NUL-terminated string.
*   (The C++ implementation needs to use getTerminatedBuffer()
*   on UnicodeString objects which end up being returned this way.)
