You just have to re-order things a bit I think, and remove the local:
$SIG{ALRM}= sub {die "TIMEOUT_PASSED\n"};
eval {
alarm (3);
printf " get character \n" ;
$data = <> ;
}; # eval the eval block should take less 3 secs otherwise , timeout function is
fired
alarm (0);
if ($@ =~ /TIMEOUT_PASSED/) {
# treat timeout
printf " TIMEOUT : no data to read \n" ;
}

Subject: Timout using eval
Hi ,
I'm trying to timeout an event , i'm searching for an implementation to perform that ,
i tried the eval die technique , but the result is not what i need , this is a sample
code :
-------------------------------
my$data;
eval {
local $SIG{ALRM}= sub {die "TIMEOUT_PASSED\n"};
alarm (3);
printf " get character \n" ;
$data = <> ;
alarm (0);
}; # eval the eval block should take less 3 secs otherwise , timeout function is
fired
if ($@ =~ /TIMEOUT_PASSED/) {
# treat timeout
printf " TIMEOUT : no data to read \n" ;
}
-------------------------------
the above code , did not wait 3 secs for the user input , it waits forever !
Could someone help please.
Thks.
