To POLL or Not To POLL the mouse

To POLL or Not To POLL the mouse

Post by Jay I Ch » Sat, 29 Jan 1994 18:40:08



I'd like to put a simple mouse support to my program.
The easiest way I can think of is polling /dev/mouse repeatedly.
However, without some delay between polls, this approach ties up
the system and in fact does not make much sense because the maximum
sampling rate is only about 50 Hz.
Unfortunately, the standard "sleep" cannot be used as a delay routine
since 1 sec interval between polls is too long.
Does anybody have better idea/technique?
Any input will be greatly appreciated.
Thanks

Hi, does anyone have sys/poll.h file and can use poll function?
I've installed gcc and all packages associated with it, but there is no
sys/poll.h file.  I'd appreciate if anyone told me where to get a library
package that contains this file/function.

thanks,
/Simon
