Re: Query on SIGFPE handling

[joy merwin monteiro <joy.merwin@gmail.com>]

The basic mistake is that the variable values have not changed.
1/0 will generate a FPE no matter what you do.
use variables like a=0;b=1;
and if b/a generates an FPE,
change its value.(bit hazy how to implement this... google around)
the reason for giving you a signal handler
is obviously to help you correct the error,
not commit it over and over again!

PS: Such questions will be better answered on linux-cprogramming list....
try it.
