Function Documentation

RCSID (  "$Id:wordvec.  c, v 1.7 2005/06/25 01:37:43 daichik Exp $"  )

void word_vec_close (  void   )

Terminate matching data structures.

void word_vec_free (  word_vec_t *  wovec, guint  n )

Release a word vector, containing `n' items.

void word_vec_init (  void   )

Initialize matching data structures.

guint word_vec_make (  const gchar *  query_str, word_vec_t **  wovec )

Given a query string, return a dynamically built word vector, along with the amount of items held into that vector. Words are broken on non-alphanumeric boundaries. Returns: the amount of valid items in the built vector, and fill `wovec' with the pointer to the allocated vector. If there are no items, there is no vector returned.

word_vec_t* word_vec_zrealloc (  word_vec_t *  wv, gint  ncount )  [static]

Reallocate a word-vector from the zone into heap memory, to hold `ncount'.

Variable Documentation

zone_t* wovec_zone = NULL [static]

Word-vectors of WOVEC_DFLT entries.
