Delphi is the premier development tool within Windows computing, and communications is one of the fastest growing segments of the Windows development platform. The Tomes of Delphi: Basic 32-Bit Communications Programming focuses on two essential communications technologies—Windows Sockets and the Telephony Application Programming Interface—and provides a guide to using them in Windows applications.

The book is divided into sections on Winsock and TAPI. Each section begins with an introductory chapter on that particular technology and following chapters discuss basic TAPI and Winsock programming and their functions. Each function entry contains the syntax, a description of what the function does, a list and description of parameters, acceptable constant values, return values, cross-references to related functions, and an example of its use. Where appropriate, the authors develop wrapper classes and components to further facilitate communications programming.

The appendixes include a glossary of communications terms and Winsock and TAPI error codes.
