Buffering linewise might prevent commands to be buffered before HaChu actually starts to read them. --- diff --git a/hachu.c b/hachu.c index 52355e8..fdf5bb4 100644 --- a/hachu.c +++ b/hachu.c @@ -2646,16 +2646,18 @@ printf("# ponder hit\n"); main() { - int engineSide=NONE; // side played by engine + int engineSide=NONE; // side played by engine MOVE move; int i, score, curVarNr; - Init(V_CHU); // Chu + setvbuf(stdin, NULL, _IOLBF, 1024); // buffering more than one line flaws test for pending input! + + Init(V_CHU); // Chu seed = startTime = GetTickCount(); moveNr = 0; // initialize random while(1) { // infinite loop - fflush(stdout); // make sure everything is printed before we do something that might take time + fflush(stdout); // make sure everything is printed before we do something that might take time *inBuf = 0; if(moveNr >= 20) randomize = OFF; //if(moveNr >20) printf("resign\n");
