Cogent provides a free application programming interface (API) for the Cascade DataHub, documented in the Cogent C API manual. This API consists of a C code library and documented examples that allow you to integrate the DataHub into your own applications. The API allows you to read, write and have your programs register for exceptions with the DataHub. The example code to do this is provided at the end of the Cogent C API manual.

The API is available for download from the Cogent Web Site (http://www.cogent.ca). If you have problems downloading the API from our web site, please contact Cogent and we can arrange to have the API sent to you on diskette.
