Thanks but the question is what does Option does?
I think that parallel code is not relevant here because I see no reason to use
ReadPgn during games or analysis.
I have function setboard that get a fen and put it as board position but I do
not understand what Crafty exactly does.
Another question is if there are no potential bugs in Crafty in reading pgn
I found the following strings as global variables
char pgn_event[32] = {"?"};
char pgn_site[32] = {"?"};
char pgn_round[32] = {"?"};
char pgn_date[32] = {"????.??.??"};
char pgn_white_elo[32] = {""};
char pgn_white[64] = {"unknown"};
char pgn_black_elo[32] = {""};
char pgn_black[64] = {"crafty " VERSION};
char pgn_result[32] = {"*"};
Crafty also has value[128] as a local variable.
I wonder what happens if the pgn has more than 32 chars in the pgn_event
I am afraid that strcpy(pgn_event,value) that is used in Crafty will not work
correctly in that case and Crafty use it in
if (strstr(input_buffer,"Event")) strcpy(pgn_event,value);
Same for other fields of the pgn.
