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