gb2049 has asked for the wisdom of the Perl Monks concerning the following question:
Hello,
I have an application (running in windowXP) that is writing debug data to a text file. When I send Ctrl-C to the window through GUITest, it interrupts the application and everything is good.
I then tried sending the interrupt signal through a perl script with the following code:
kill(3,$pid); # 3 is the INT value on my system
The results I get from the using kill is different than using ctrl-c (missing some debug output near the end).
Any help will be greatly appreciated.
Thanks,
Robert

yea its 3 on mine
I get it after running this:
foreach $name (split(' ', $Config{sig_name})) {
$i++;
printf "%3d) %s \t", $i, $name;
if (($i % 5) == 0) { print "\n"; }
}
print "\n";
1) ZERO 2) HUP 3) INT 4) QUIT 5) ILL
6) NUM05 7) NUM06 8) NUM07 9) FPE 10) KILL
11) NUM10 12) SEGV 13) NUM12 14) PIPE 15) ALRM
16) TERM 17) NUM16 18) NUM17 19) NUM18 20) NUM19
21) CHLD 22) BREAK 23) ABRT 24) STOP 25) NUM24
26) CONT 27) CLD

Shouldn't you start counting from 0 instead of 1 ?
