Re: [pygame] Battery Life



>What does strace show your process doing?

While the process is idling it shows repeated:

select(0,NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
select(5, [4], NULL, NULL, {0, 0})           = 0 (Timeout)
select(0,NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
select(5, [4], NULL, NULL, {0, 0})           = 0 (Timeout)
select(0,NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
select(5, [4], NULL, NULL, {0, 0})           = 0 (Timeout)

...and so on

I assume this polling is the underlying pygame implementation of pygame.event.wait(). Wonder if there's any more efficient way?

Thanks,
Doug

What does strace show your process doing?
