Where are datatypes declared?

The header file cstypes.h contains type definitions (typedefs) for all of the Open Client and Open Server datatypes. The cstypes.h file is included in Client-Library applications using ctpublic.h—there is no need to include it explicitly.

An application declaring program variables uses these type definitions in its declaration section. For example:

CS_CHAR          buffer[40];

CS_INT           result_type, count;

CS_MONEY         profit;
