| * \brief C API: Transliterator |
| * |
| * <h2> Transliteration </h2> |
| * The data structures and functions described in this header provide |
| * transliteration services. Transliteration services are implemented |
| * as C++ classes. The comments and documentation in this header |
| * assume the reader is familiar with the C++ headers translit.h and |
| * associated documentation. |
| * |
| * A significant but incomplete subset of the C++ transliteration |
| * services are available to C code through this header. In order to |
| * access more complex transliteration services, refer to the C++ |
| * headers and documentation. |
| * |
| * There are two sets of functions for working with transliterator IDs: |
| * |
| * An old, deprecated set uses char * IDs, which works for true and pure |
| * identifiers that these APIs were designed for, |
| * for example "Cyrillic-Latin". |
| * It does not work when the ID contains filters ("[:Script=Cyrl:]") |
| * or even a complete set of rules because then the ID string contains more |
| * than just "invariant" characters (see utypes.h). |
| * |
| * A new set of functions replaces the old ones and uses UChar * IDs, |
| * paralleling the UnicodeString IDs in the C++ API. (New in ICU 2.8.) |

| * Return the ID of the index-th system transliterator. The result |
| * is placed in the given buffer. If the given buffer is too small, |
| * the initial substring is copied to buf. The result in buf is |
| * always zero-terminated. |
| * |
| * @param index the number of the transliterator to return. Must |
| * satisfy 0 <= index < utrans_countAvailableIDs(). If index is out |
| * of range then it is treated as if it were 0. |
| * @param buf the buffer in which to receive the ID. This may be |
| * NULL, in which case no characters are copied. |
| * @param bufCapacity the capacity of the buffer. Ignored if buf is |
| * NULL. |
| * @return the actual length of the index-th ID, not including |
| * zero-termination. This may be greater than bufCapacity. |
| * @deprecated ICU 2.8 Use utrans_openIDs() instead, see utrans.h |
