Hi all,

While running a tcl script in tclsh,
I want block keystroke combinatination ctrl+c so that my program can
run in uninterrupted environment.

Can somebody suggest a solution for this.

On *nix systems you can just put the script into the background:

$ tclsh myscript.tcl &

On both windows and *nix you can use job control features of the
shell.

My personal favorite system is daemontools which starts/stops/pauses/
restarts etc. a foreground application. It is much easier to work with
foreground running applications and daemontools (http://cr.yp.to/
daemontools/svc.html) works great.

Since the program is not running on a console, you can't really send
keyboard commands to it.

The other possibility is to use the stty utility to switch the
terminal into raw mode. Like that the program will still respond to
the signal, but Ctrl+C won't generate it.

TclX and
package require tclX
signal -restart ignore SIGINT

expect
package require expect
trap SIG_IGN SIGINT

have signal handling ( for unixies ).

set the signal handler to ignore or insert your
own handler for SIGINT
