Pointer - Object Oriented Memory Pointers in Pure Perl ...

    https://metacpan.org/pod/Pointer
    Apr 27, 2005 · This module allows you to create Perl objects that emulate C pointers. You can use them to read and explore the memory of your Perl process. Pointer.pm (and every subclass) exports a function called pointer that returns a new pointer object. Each object has a type like (void, int, long, sv).

pointers in perl - LinuxQuestions.org

    Apr 10, 2005 · basically a good way to think about pointers or reference in perl is to think that pointers are a special kind of scalar. So when initalizing a pointer you need create a "special scalar". However pointers can be of two things in perl. One is a regular reference like in C. and another kind of reference is an anonymous copy.

Dereferencing in perl

    http://www.perlmeme.org/howtos/using_perl/dereferencing.html
    Dereferencing in perl. References are commonly used when you are returning a large object or data structure (for example an array or hash) from a subroutine. Instead of returning a copy of the entire data structure, you return a pointer to the structure. This makes your programs more efficient. You can also use references to subroutines and scalars.

Day 18 -- References in Perl 5

    http://wwwacs.gantep.edu.tr/docs/perl-ebook/ch18.htm
    A reference is simply an address to a value. How you use that value is up to you as the programmer and what the language lets you get away with. In Perl, you can refer to a pointer as a reference; in fact, you can use the terms pointer and reference interchangeably without any loss of meaning.

perlref - perldoc.perl.org

    https://perldoc.perl.org/perlref.html
    References are easy to use in Perl. There is just one overriding principle: in general, Perl does no implicit referencing or dereferencing. When a scalar is holding a reference, it always behaves as a simple scalar. It doesn't magically start being an array or hash or subroutine; you have to tell it explicitly to do so, by dereferencing it.

Array references in Perl - Perl Maven

    https://perlmaven.com/array-references-in-perl
    (If you are a C programmer, don't even think about pointer arithmetic. You can't do that in Perl.) Basically, if you see such value printed somewhere, you know that the code is accessing a reference to an array and that you should probably change the code to access the content of that array.

Pointers vs References in C++ - GeeksforGeeks

    https://www.geeksforgeeks.org/pointers-vs-references-cpp/
    C and C++ support pointers which are different from most of the other programming languages. Other languages including C++, Java, Python, Ruby, Perl and PHP support references. On the surface, both references and pointers are very similar, both are used to have one variable provide access to another.

Perl - References - Tutorialspoint

    https://www.tutorialspoint.com/perl/perl_references.htm
    A Perl reference is a scalar data type that holds the location of another value which could be scalar, arrays, or hashes. Because of its scalar nature, a reference can be used anywhere, a scalar can be used. You can construct lists containing references to other lists, which can contain references to hashes, and so on. This is how the nested ...
