Perl By Example is a guide to Perl that starts with the basics of Perl scripting and carries you all the way to advanced networking and Web applications. Coverage starts with statements, variables, scalars, arrays, hashes, and printing. Understand Perl operators, expressions, control structures, and file handling. Next, learn how to modularize and package Perl scripts, work with objects in the Perl environment, interface with the surrounding system, and create sophisticated reports. Using extensive examples, learn how to use Perl on the Web and in advanced networking applications that utilize message queues, semaphores, and shared memory.
An explanation of how to expand the functionality and usefulness of the Perl programming language, this guide delves into the complex issues of using real code examples from the Perl source. Detailed is how to use Perl from C programs, such as writing interfaces to C libraries, techniques on implementing Perl callbacks for C libraries, passing Perl hashes and arrays between Perl and C. Additionally, developers are provided with an API reference for the internal C interface to Perl and a reference on the typemap system. Sometimes programmers are required to go outside the core of the Perl programming language to C routines or libraries in order to get their task done. This work was written in order to help software writers relate Perl and C. Assuming that readers are knowledgeable in Perl, they explain how to embed C into programs. In addition they also address cases where Perl is not the best base language and explore the opposite case.
