3/28 I have a process that has to set the signal handlers for tty
generated signals (and some others) to ignore while it is
doing some critical processing. When this processing is done
it calls exec to start executing a different pgm. I want to
reset the signal handlers to their original values before exec
is called. What is the easiest way to do that?
\_ for (i = 1; i < _SIG_MAXSIG; i++) signal(i, SIG_DFL);
If you don't actually want to ignore the tty signals, but just
defer them until your critical processing is done, you can use
sigprocmask instead of actually ignoring them; then you won't
have to do anything at all when you call exec.
\_ sigprocmask seems to do what I want. I was just calling
signal and storing the old ptr in an array and then just
restoring them prior to calling exec, but sigprocmask
sounds better. thanks.
\_ WTF does this have to do with Iraq or RIDE BIKE or Linux? Get off
the motd with this stuff!
\_ If it counts for anything, my process runs on '1337 GN00
D3B14N L1NUX!
\_ use motdedit you twink.
