Network Programming with Perl

Summary

The object-oriented IO::Socket library significantly simplifies network programming by eliminating much of the "noise code" handed down from the socket API's C heritage and replacing it with a clean and convenient interface. Throughout the remainder of this book we create IO::Socket objects using the class's flexible new() method, and use its object methods whenever they offer a clear syntactic advantage (e.g., $sock->accept()). In cases where there is no clear syntactic advantage, for example between read ($sock,$data,1024) and $sock->read ($data,1024), we use the Perl built-ins in order to benefit from the performance gains.

With the IO::Socket module it is easy to write simple client and server programs, such as the Web client and ...
