Corporations now use demographic information to target their marketing campaigns, forecast sales, determine market penetration, assess market potential, and more.
Demographic coding of existing databases is an important part of this process. Demographics Library is an easy-to- embed multi-platform Application Programming Interface (API) that allows you to append valuable demographics to your own databases.
This document contains reference information for all API elements of Demographics Library. The API is available as a DLL for 64-bit Windows developers and as a C Language library for UNIX developers. The functions within this API allow developers to retrieve demographic information from Precisely demographic data files. A separately-licensed loader program is also available for converting other data files into the format used by the Demographics Library.
This document provides information about the general use of the Demographics Library API, as
well as a complete function reference. A README.TXT file would contain any
modifications or corrections to this document. Always assume that the information in
README.TXT supersedes the printed documentation.
Within this manual, all language references that appear embedded in descriptive text, including function, macro and variable references, will be shown in a monospaced Courier font:
x = 1; // Just a sample.
Function names embedded in text are shown in bold.
Both decimal and hexadecimal numbers may be used in this document. Hexadecimal numbers are always preceded by 0x:
0x1F// hex 1F
0x04// hex 04
12// decimal 12
While the API is accessible to a variety of programming languages, code examples, function declarations, and comments are given in C. Within Demographics Library, you will find that all of the public functions begin with "D1", such as D1Find. Where possible, you should avoid using variable names, constant names or macro names beginning with D1. Check the include file in your development environment's directory for a complete list of visible symbols.
