+ input data:
+ word:      input word
+ word_size: byte length of the input word
+ 
+ hyphens:   allocated character buffer (size = word_size + 5)
+ hyphenated_word: allocated character buffer (size ~ word_size * 2) or NULL
+ rep, pos, cut: pointers (point to the allocated and _zeroed_ buffers
+                (size=word_size) or with NULL value) or NULL
+
+ output data:
+ hyphens:   hyphenation vector (hyphenation points signed with odd numbers)
+ hyphenated_word: hyphenated input word (hyphens signed with `='),
+                  optional (NULL input)
+ rep:       NULL (only standard hyph.), or replacements (hyphenation points
+            signed with `=' in replacements);
+ pos:       NULL, or difference of the actual position and the beginning
+            positions of the change in input words;
+ cut:       NULL, or counts of the removed characters of the original words
+            at hyphenation,
+
+ Note: rep, pos, cut are complementary arrays to the hyphens, indexed with the
+       character positions of the input word.
+
+ For example:
+ Schiffahrt -> Schiff=fahrt,
+ pattern: f1f/ff=f,1,2
+ output: rep[5]="ff=f", pos[5] = 1, cut[5] = 2
+
+ Note: hnj_hyphen_hyphenate2() can allocate rep, pos, cut (word_size
+       length arrays):
+
+ char ** rep = NULL;
+ int * pos = NULL;
+ int * cut = NULL;
+ char hyphens[MAXWORDLEN];
+ hnj_hyphen_hyphenate2(dict, "example", 7, hyphens, NULL, &rep, &pos, &cut);

+ See example in the source distribution.
