NAME

       errstr - lookup error codes

SYNOPSIS

       openssl errstr error_code

DESCRIPTION

       Sometimes an application will not load error message and only numerical forms will be available. The errstr utility can be used to display
       the meaning of the hex code. The hex code is the hex digits after the second colon.

EXAMPLE

       The error code:

	27594:error:2006D080:lib(32):func(109):reason(128):bss_file.c:107:

       can be displayed with:

	openssl errstr 2006D080

       to produce the error message:

	error:2006D080:BIO routines:BIO_new_file:no such file

NAME

       Razor::Errorhandler - Error handling mechanism for Razor.

SYNOPSIS

	   package Foo;

	   use Razor::Errorhandler;
	   @ISA = qw(Razor::Errorhandler);

	   sub alive {
	       ..
	       ..
	       return
	       $self->error ("Awake, awake! Ring the alarum bell. 
			      Murther and treason!", $dagger)
		   if $self->murdered($king);
	   }

	   package main;

	   use Foo;
	   my $foo = new Foo;
	   $foo->alive($king) or print $foo->errstr();
	   # prints "Awake, awake! ... "

DESCRIPTION

       Razor::Errorhandler encapsulates the error handling mechanism used by the modules in Razor bundle. Razor::Errorhandler doesn't have a
       constructor and is meant to be inherited. The derived modules use its two methods, error() and errstr(), to communicate error messages to
       the caller.

       When a method of the derived module fails, it calls $self->error() and returns  to the caller. The error message passed to error() is made
       available to the caller through the errstr() accessor. error() also accepts a list of sensitive data that it wipes out (undef'es) before
       returning.

       The caller should never call errstr() to check for errors. errstr() should be called only when a method indicates (usually through an undef
       return value) that an error has occured. This is because errstr() is never overwritten and will always contain a value after the occurance
       of first error.

METHODS

       error($mesage, ($wipeme, $wipemetoo))
	   The first argument to error() is $message which is placed in $self->{errstr} and the remaining arguments are interpretted as variables
	   containing sensitive data that are wiped out from the memory. error() always returns undef.

       errstr()
	   errstr() is an accessor method for $self->{errstr}.
