Re^4: using $SIG as an IPC interrupt?

in reply to Re^3: using $SIG as an IPC interrupt?
in thread using $SIG as an IPC interrupt?

I'm not sure I understand - are you saying there is a separate set of SIG signals per user? ie. that if an application running as root generates a SIGUSR1 it will be ignored by my perl code?

(This is running on Solaris BTW)

Thanks!

I'm saying that if your app runs as user `$foo`, and another program runs as user `$bar`, that other program can't send signals to your program, except when `$foo eq $bar` or `$bar eq 'root'`	[reply] [d/l] [select]

Thanks. Do you by any chance have an example for how to generate the SIGUSR signal from the c program?	[reply]

`man 2 kill` should help.	[reply] [d/l]
