A move is an array of bytes, which are simply gint8s. A move is a sequence of movelets terminated by -1. A movelet is a sequence of 3 bytes which describes what happens to a particular square in the board. Movelet format is "x y val" where val is the new value of the square (x, y). Thus the move corresponding to "1. e4" in chess is "4 1 0 4 3 6 -1" (i.e, square (4, 0), which means e2 becomes empty, and square (4, 3), which is e4, becomes 6, assuming that white pawn is represented by 6. Note that row and col numbers start from 0.) When the move is written to file or sent to the engine, it will be converted to a human friendly format.

|
Returns the inverse of a move in the given board. The move format does not specify the old value of the squares. So it is not possible to go from the new Pos to the old Pos. To be able to do this we need to get the "inverse" of the move using the current board Definition at line 171 of file move.c. Referenced by ab_with_tt_incr(), and movstack_push(). |

Compares two moves byte by byte. Literal not semantic comparison. Returns TRUE if the moves are equal.

Makes the move src to the move dest. Memory is assumed to have already been allocated for dest. Definition at line 35 of file move.c. Referenced by ab_dfid(), ab_with_tt(), and ab_with_tt_incr(). |

Make a copy of the move. The new move is malloc()d and so must be free()d by the caller. Definition at line 160 of file move.c. Referenced by ab_with_tt(), hash_insert(), mov_getinv(), and movstack_push(). |
