Hey Guys,

I’ve created some Window’s processes uing the Win32/Process (by Daniel  
Berger) library. When I send a signal to these processes using  
Win32/Process.kill([1,3…9], pid), the processes are always killed.  
I’ve tried trapping for the signal using both a rescue and Signal.trap()  
clause with no luck.

I know that the Unix versions of the Process library allow you to  
capture the signal with a rescue clause for either SignalException or  
Interrupt Exceptions. Anyone know if the Win32/Process implements  
similar behavior for signals or failing that if anyone has a workaround.

Sonny.

Only the following signals are supported.

_SIGABRT_ Abnormal termination _SIGFPE_ Floating-point error _SIGILL_  
Illegal  
instruction _SIGINT_ CTRL+C signal _SIGSEGV_ Illegal storage access  
\*SIGTERM

- Termination request  
You can try using the cygwin or mingw version of command line signals,  
but I  
am not sure if they solve your problem. Unlike in \*nix it is better not  
to  
use signals for process communication on windows platform. It is better  
to  
use pipes/sockets/events.
