After you generate method skeletons, prototypes, and implementation templates, write the code for each method in the method implementation file. You can include C or C++ functions in C components. EAServer provides C routines for common C component tasks (see Chapter 5, “C Routines Reference,” in the EAServer API Reference).
To adapt a C++ class for use as a C component, you must write C wrappers. For details, see “C components that are wrappers for C++ classes”.
EAServer Manager creates template files for each method when you define the method signatures (or method prototypes) and generate skeleton routines. You can modify the template files to implement the method bodies, or you can code your methods from scratch according to the rules laid out here.
Function overloading is not supported for C components.
You can also include EAServer routines to:
Customize the creation and destruction of components
Manage instance data
Share data between components
Connect to third-tier database servers
Call other components
Send result sets
Set transaction state
Write to a log file
