7.11 lou_hyphenate ¶

int lou_hyphenate (
  const char *tableList,
  const widechar *inbuf,
  int inlen,
  char *hyphens,
  int mode);

This function looks at the characters in inbuf and if it finds a sequence of letters attempts to hyphenate it as a word. Note that lou_hyphenate operates on single words only, and spaces or punctuation marks between letters are not allowed. Leading and trailing punctuation marks are ignored. The table named by the tableList parameter must contain a hyphenation table. If it does not, the function does nothing. inlen is the length of the character string in inbuf. hyphens is an array of characters and must be of size inlen + 1 (to account for the NULL terminator). If hyphenation is successful it will have a 1 at the beginning of each syllable and a 0 elsewhere. If the mode parameter is 0 inbuf is assumed to contain untranslated characters. Any nonzero value means that inbuf contains a translation. In this case, it is back-translated, hyphenation is performed, and it is re-translated so that the hyphens can be placed correctly. The lou_translate and lou_backTranslate functions are used in this process. lou_hyphenate returns 1 if hyphenation was successful and 0 otherwise. In the latter case, the contents of the hyphens parameter are undefined. This function was provided for use in liblouisutdml.
