Detailed Description

Initialize the trap table.

Fill in w_table1_1[]. Each entry in Mem_FILE, as well as its three rotations, are added to w_table1_1[]. Four entries in w_table2_1[] are generated from one entry in w_table1_1[]. a_plain b_plain Each line in MEM_FILE is in the following format:

a_plain b_plain

where a_plain = stones that must be present for a first level trap. where b_plain = stones that must be empty for a first level trap.

static int _add_word2 (  W_ENTRY *  word, int  index )  [static]

Add an entry to w_table2_1[]. Parameters: word  W_ENTRY * : entry to be added to w_table2_1[index]. index  int : index into w_table2_1[]. Returns: int : the next open index in w_table2_1[]. This results in 4 new entries in w_table2_1[].

static short _nextbit (  short  plain, int  offset )  [static]

Shift the next (from postion offset) on bit to the right most postion. Parameters: plain  short : input plain. offset  int : first position to start at. Returns: short : plain rotated to the right so that the first on bit to the left of offset is now the right-most bit.

w_init_1 (  void   )

Initialize the trap table. Returns: void.
