The below code works perfectly on my ubuntu desktop but fails on BBB
ubuntu! In the code I'm reading from usb GPS device /dev/ttyUSB0. Loop
breaks when device is unplugged and waits 90 seconds to reopen the device
and start reading. On BBB when GPS device is unplugged CPU is 100% used
void main(){
opendevice:
FILE *f = fopen("/dev/ttyUSBS0", "r");
c = (char) getc(f);
while (c != EOF) {
if (c == '@') {
i = 0;
c = getc(f);
while (c != '#') {
if (c == EOF) {
break;
}
buf[i] = c;
i++;
c = getc(f);
}
buf[i] = '\0';
printf("%s\n",buf);
} else if (c == -1) {
break;
}
c = (char) getc(f);
}
sleep(90);
goto opendevice;
}
I'm speculating that getc function is not returning correct EOF character
on device unplug.
