介绍如何扩大Perl编程语言的功能性和实用性的指南，本指南中深入探讨了利用真正的Perl源代码示例的复杂问题。详细的是如何从C程序，如编写的Perl C库接口，在执行C库Perl的回调技术，在Perl和C之间传递Perl的哈希和数组，此外，为开发人员提供了一个针对Perl的内部的C API参考和typemap系统的引用参考。-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.
