static void sb_init_entry (  void   )  [static]

initialize the static s_init_entry variable once and only once. This is used to zero out the key so that if the compiler pads the structure, we still have 0's in this keylookup. Definition at line 263 of file scoreboard.c. References memset. Referenced by scoreboard_init().

int scoreboard_add (  SCOREBOARD *  sbp, u_int32_t *  address, SCORE_ENTRY **  sepp )

Referenced by flowps_add_entry(), and scoreboard_move().

static int scoreboard_anrfree (  void *  key, void *  data )  [static]

int scoreboard_init (  SCOREBOARD *  sbp, char *  description, TRACKER_POSITION  kind, unsigned int  rows, int  memcap )

Create a new scoreboard for tracking nodes. Parameters: sbp  scoreboard to initialize at_thr  active talker thresholds sc_thr  scanner thresholds (may not be needed) kind  tracker location for this table description  table description rows  number of rows to populate the initial HASHTABLE() with memcap  bytes we can spend on this scoreboard Returns: FLOW_SUCCESS on success, else failure Definition at line 28 of file scoreboard.c.

int scoreboard_move (  SCOREBOARD *  dst, SCOREBOARD *  src, u_int32_t *  address )

Move a scoreboard entry from one table to the other Todo: This actually can probably be done faster with the rindex stuff and a SFXHASH_NODE interface.
