Detailed Description

A namespace for all chess related objects that are not related to the GUI.

Typedef Documentation

typedef uint64_t cwchess::mask_t

The type of an internal BitBoard mask.

Don't use this, use BitBoard .

Definition at line 48 of file BitBoard.h.

Function Documentation

Index cwchess::mask2index ( mask_t  mask )

inline

Convert a single bit mask into it's Index.

The provided mask should have a single bit set. However, if that is not the case, then this function returns either 64 if no bit is set, or the index of the first (least significant) bit that is set.
