Functions
int	ParseSquare2 (const char *s)
	Parse "e2" style coordinate into a 120-based square index.
int	ParsePromotionPiece (char c, int side)
	Map promotion char ('q','r','b','n') to a piece code for the given side. Case-insensitive. Returns EMPTY if none/unknown.
int	LegalMovesFrom (S_BOARD *pos, int from, int outMoves[], char labels[][8], int maxOut)
	Build list of legal moves that originate from from.
int	MatchDestinationMove (S_BOARD *pos, int from, const char *destStr, const int legalMoves[], int nMoves)
	Resolve a destination string ("e4", "e8=Q", "e8q") to a move.

Function Documentation

LegalMovesFrom()

int LegalMovesFrom	(	S_BOARD *	pos,
		int	from,
		int	outMoves[],
		char	labels[][8],
		int	maxOut )

Build list of legal moves that originate from from.

Parameters

pos	Board state.
from	120-based from-square.
outMoves	Output array of encoded moves.
labels	Output labels (e.g., "e4", "e8=Q"), each [8].
maxOut	Capacity of outMoves/labels.

Returns

Count of legal moves written (<= maxOut).
