Dolphin Application Development

Dolphin application development is straightforward. Since Dolphin is DOS-compatible, most of the application can be tested on a desktop computer.

Compiling Applications for the Dolphin

Although the operating system on the Dolphin 7200 is DOS-compatible, it provides many unique features that are not built into most PCs. For example, it has an integrated bar code scanner. The Dolphin libraries provide an API that allows an application to use these features.

There are four libraries provided for linking into applications:

dolphins.lib	for small memory models
dolphinm.lib	for medium memory models
dolphinc.lib	for compact memory models
dolphinl.lib	for large memory models

The header file, dolphin.h, in the c:\dolphXX\devtools\ directory contains useful declarations for using these libraries.

Sample Applications

A number of sample programs with source code have been provided with your Dolphin terminal. The sample programs are installed in the c:\dolphXX\devtools\samples directory on your desktop computer.
