     15 *
     16 *   Test of the C wrapper for the DateTimePatternGenerator.
     17 *   Calls each C API function and exercises code paths in the wrapper,
     18 *   but the full functionality is tested in the C++ intltest.
     19 *
     20 *   One item to note: C API functions which return a const UChar *
     21 *   should return a NUL-terminated string.
     22 *   (The C++ implementation needs to use getTerminatedBuffer()
     23 *   on UnicodeString objects which end up being returned this way.)
