Hallo,
I have to use timer because I have to communicate with other programm via
filestream
and I use this timer also for scheduling the time that I have to send data
to my device.
people said if I use interrupt so I can be sure I will not lose my datas.
here is my routine
....
while(1)
{
res=select(fd+1, &rfds, NULL, NULL, &tv);
if(res==0)
{
tries++;
if(tries==8)
return 0;
}
n = read (fd, p, 1);
if(n>0)
{
printf(" %X \n", buffer[rd]);
p++;
rd++;
}
// up here I analyze my datas.
// if everythings ok I jump out of the while
return rd;
}
....
best regards
sayangoin
