Re: using $! for die()ing with Package function

I think as long as a failed open() or mkdir() (IE a system function that does $! sets it already) then that is all I need for this project: sub baz { mkdir '/dir/I/cant/make' or return; } will do what i need: baz or die $!; Actually mkdir returns true or false - sub baz{return mkdir '/dir/I/ca

I think the misunderstanding is: $! is not a general purpose error message, it is a magical wrapper around errno() (read the section in perlvar) You *COULD* set $! to some numeric value selected from errno.h if there was one close enough to your message. But a user of your library getting "Di

Re: Spam:Re: using $! for die()ing with Package function

I don't think you can't set $! since it is a system var. Perhaps you could do something like: my $err_text; die $err_text if !Foo(); sub Foo_baz { return 1 if shift; $err_text = "Your error message." return 0; } Thanks Ron, yeah if I want to I'll have to pro

perldoc Carp; If that doesn't do what you want, then: perldoc -f eval else just set $@ and return undef. This is a bad solution I think. Jonathan Paton -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

using $! for die()ing with Package function

Howdy folks, Here's something I was wondering (and wondering why its never come up sooner for me ;p) if I make a module, say Foobar.pm how do you make it so if a function returns false you can die $!; ? package Foobar; sub baz { return 1 if shift; # do what here to set $! = "You are not true"
