e-Biz Impact supports two types of C++ and C-based applications:
Client (acquire)
Server
Client applications can only make DFCs. After a C++ or C-based client application initializes, the entry point function (of acquire type) is called, and code execution occurs.
Server applications can both make and service DFCs. When a DFC request arrives, the corresponding function implementing DFC is called.
For example, inside the acquire type entry point function, a DFC call is made. The DFC reaches the servicing application. If the server application is also a C++ or C-based application, the function implementing that DFC is called, and a return value is sent to the client application, which sees the DFC as a regular c function that it can call to process data.
