masking interrupts
Posted: Wed Aug 26, 2009 4:32 pm
hi
when i mask a specific interrupt by sending a byte to port 0x21, what happens when i reenable that interrupt again later? will any masked interrupts now be triggered or are they lost?
if they're lost, is there anything similiar to signals, where i can block specific signals with sigprocmask and then receive them later by unblocking them??
thanks
