Reference/Example Programs
The API distribution contains a number of example programs. These can all be found beneath the examples/ subdirectory.
All example programs are available in both C and C++ variants: Each C source file has a corresponding C++ version with the prefix cpp.C. For example, the database.c source file has a databasecpp.C twin.
The reference/ sub directory contains the basic usage examples and it's recommended for new users to start with these. The programs include:
| database.c | How to use the core database interfaces including how to define database structure, populating databases and running queries. |
|---|---|
| filesave.c/fileload.c | How to save and retrieve databases to/from disk. |
| client.c/server.c | How to send databases across networks using both tcp/ip and udp/ip protocols. |
| dates.c | How to use the es_date (date calculator) interface. |
| statistics.c | How to use the es_sc (statistics calculator) interface. |
The mesh/, tick/ and risk/ sub-directories each contain complete sample applications or case studies that are more advanced. Refer to corresponding README.txt files for usage instructions:
| mesh | Application for generating and saving polygonal mesh data to a virtual database comprised of a grid of distributed in-memory database servers. Includes mesh rendering (see image on home page) client app. |
|---|---|
| tick | Application for saving and retrieving a sequence of financial market "tick" data. |
