Do any one knows the procedure of NON-BLOCKING reed() command for HID events in LINUX
Currently I am using
read(fd, ev, sizeof(struct hiddev_event) * EV_NUM);
But it goes to BLOCKING stage, when my HID pointing device is NOT towards the sensoer bar
Kind regards,
Madni
I think more information is needed to answer this question. Most of the USB HID APIs that I have looked at put an asynchronous flag in the Open() method. In general, you’re not going to want to do an asynchronous read one time, then follow that with a synchronous read. All your read() calls should use the same technique.
Are you using the O_NONBLOCK flag when you open the device?
