Function Documentation

moveToString()

char * moveToString ( int move )

extern

Convert an encoded move to coordinate notation.

Parameters

move	Encoded move integer.

Returns

Pointer to a static string containing the move (e.g., "e2e4", "e7e8q").

Note

This uses a static buffer and is not thread-safe.

Parameters

ptrChar	Pointer to a string containing the move (e.g., "e2e4", "e7e8q").
pos	Pointer to the current board state.

Returns

Encoded move integer, or NOMOVE if invalid.

Parameters

list	Pointer to the move list to print.

squareToString()

char * squareToString ( int sq )

extern

Convert a board square index to algebraic notation.

Parameters

sq	Board square index (0–119 in mailbox 120 format).

Returns

Pointer to a static string containing the square (e.g., "e4").

Note

This uses a static buffer and is not thread-safe.
