sure it can be some bug by me. but how? I use timestamp.
I got the move of the opponent and the time 5800 command and then set my
internal clock to 58 sec rest time and began to think. after 1 second, I lost on
time. The winboard also showed 1 sec remaining, but in the logfile was 58 secs.
I do not understand it any way.
I give my moves to winboard with normal printf("move E2E4\n"). At the beginning
of the program I use setbuf(stdout,NULL) to disable buffering. I make no fflush
at all. Is it needed?
On Input I use
rr=read(0,&buffer,1) and nothing else.
Is there something wrong about it?
Werner
do anybody of you use the "time" command comming from winboard to update your
time?
