I'm writing code that is
fork()able and within that code I want to be able to catch and log all signals whether or not they kill the code (of course, not TERM). So, after trying a few options (including
$SIG{__DIE__} and
END{};) I came up with the following code which does what I want it to do. What I'm curious about is whether or not there is anything wrong with this pragma and if there is a better(tm) way to do it.
I did a search and found some ideas using Carp and eval()'s but felt that since this program is already 99.9% done being written, it's on a deadline, and it's working quite well that this would be an acceptable way of getting what I want.
TIA
72 ## Place this first.
73 for my $sig ( keys(%SIG) )
74 {
75 $EXIT++;
76 outmsg(' Processing handler: '.$sig.'('.$EXIT.')',1);
77
78 $SIG{$sig} = sub
79 {
80 outmsg('Caught signal: '.$sig.'...dying
+.',2,$EXIT);
81 };
82 }
83
84 ## Then any specific handlers here...next.
85 $SIG{USR1} = sub
86 {
87 ## Make sure that the process is in a sleep state so that
88 ## we don't inadvertently interrupt a run cycle.
89 if ( $SLEEPING )
90 {
91 outmsg(' CAUGHT USR1! -- pre-empti
+ng sleep '.
92 'schedule.',10);
93 _main();
94 }
95 };
