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.
