[lug] Returning from select

[Budyanto Himawan]

Hi,

Does anybody know what is the trigger that causes
a select system call to return?

Say I'm doing a select on a read fd set with 50ms.
I know if none of the fds in the set becomes readable
after 50ms, select returns 0.

If I have 4 fds and 1 becomes readable.
Would select immediately return or would it wait 
for 50 ms and then return however number of fds
readable at that time?

Thanks
