Erwin Data Structures 2.1.88591 (Default branch)
ImageThe Erwin library is a very efficient and robust data structure templatelibrary for C and C++. No templates are used; a Perl script generatesC files. Vectors (dynamic arrays), lists, and hash tables (maps) ofarbitrary key and value types are provided. Several tools are includedfor auto-generating a C interface around C++ libraries, C++ extensionslike slots/properties, symbol (=hashed string) management, sophisticatedassertion macros, and documentation extraction.License: Freely DistributableChanges:
Integer overflows leading to unexpected orderingswere fixed from many comparison functions. CMakesupport was added. Two more bit operations fromHacker's Delight were added.Image

Signalsafe data structures

Hello, I have a signal handler which manipulates a data structure. The data structure's operations aren't atomic.

shared memory - userdefined data structures

Hello, I wonder if I can write my userdefined data structures(ex: a list) to a shared memory segment? I know, the shm functions get (void*) parameter so I should be able to read and write a list into the shared memory. may someone inform and clarify me about that, please? (1 Reply)

NAME

       Clone - recursively copy Perl datatypes

SYNOPSIS

	 package Foo;
	 use parent 'Clone';

	 package main;
	 my $original = Foo->new;
	 $copy = $original->clone;

	 # or

	 use Clone qw(clone);

	 $a = { 'foo' => 'bar', 'move' => 'zig' };
	 $b = [ 'alpha', 'beta', 'gamma', 'vlissides' ];
	 $c = Foo->new;

	 $d = clone($a);
	 $e = clone($b);
	 $f = clone($c);

DESCRIPTION

       This module provides a clone() method which makes recursive copies of nested hash, array, scalar and reference types, including tied
       variables and objects.

       clone() takes a scalar argument and duplicates it. To duplicate lists, arrays or hashes, pass them in by reference. e.g.

	   my $copy = clone (@array);

	   # or

	   my %copy = %{ clone (\%hash) };

SEE ALSO

       Storable's dclone() is a flexible solution for cloning variables, albeit slower for average-sized data structures. Simple and naive
       benchmarks show that Clone is faster for data structures with 3 or less levels, while dclone() can be faster for structures 4 or more
       levels deep.
