| |
Hello
main() { .... signal (SIGIO, signalhandler() ) ; .... sleep (65535) ; .... }
signalhandler() { ... }
Assume the frequency of IO events is faster than one event per 65535 seconds. Therefore, let's consider 65535 as infinity (sleeping foreveR). If a SIGIO arrives, main will get out of sleep and continue running, but signalhandler will be invoked too. I wanted to know if there is any order/priority for sleep() in main, and signalhandler() to be called first, or one of them is invoked first randomly (race condition) ?
I myself ran the program many times and everytime observed signalhandler responding first. But maybe it is not a rule, and it was just my chance ?
Thnx for your comment !
