I think to have a function to read pgn files.
I already have function to read data that is a move like 1.e4 and translate it
to e2e4
Now I think that I need a function to read the next game from a pgn file
As far as I see Crafty has no function to do it and I do not understand what it
exactly does.
I understand that Crafty's ReadPgn only return 0 in case of a move -1 in case of
end of file and 1 in other cases.
The following code seems to me code to skip moves in the pgn files because it
stops to read when data_read!=0
do {
data_read=ReadPGN(book_input,0);
if (data_read == -1) Print(4095,"end-of-file reached\n");
} while (data_read == 0);
If I understand correctly data_read cannot be 0 when I am out of the loop
but based on my understaind if data_read!=0 I cannot go to the else that come
later in te end of the following code
What I understand wrong?
do {
if (data_read < 0) {
Print(4095,"end-of-file reached\n");
break;
}
if (data_read == 1) {
if (strstr(buffer,"Site")) {
games_parsed++;
result=3;
}
else if (strstr(buffer,"esult")) {
if (strstr(buffer,"1-0")) result=2;
else if (strstr(buffer,"0-1")) result=1;
else if (strstr(buffer,"1/2-1/2")) result=0;
else if (strstr(buffer,"*")) result=3;
}
data_read=ReadPGN(book_input,0);
}
else do {
