Hi All,

drainSelfPipe() function will read the data and remove it from the descriptor?

Coz the signal (SIGUSR1) is writing sata to selfPipe descriptor but unable to wake up latch on select system call.

Data is not avaialable at select in WaitLatch fun. Coz it is read by drailSelfPipe().

So How will the SIGUSR1 can wake up the latch(select in WaitLatch Fun)??

Plz Reply..
