Hi:

What does this piece of C code do ?

------------------------------------------------------------
volatile sig_atomic_t caught_signal;

static void signal_handler(int signo)
{
        caught_signal = signo;
}
------------------------------------------------------------

I saw this code snippet in DragonFly installer code.
Interestingly enough the OS installer has a CGI based interface. 
DFly guys use Thomas Boutell CGI library. Pretty neat idea!

thanks
Saifi.
