To develop a plug-in shared library, do the following steps:

1. Write C language plug-in implementation functions for the actual business logic. These functions are not required to be exposed from the shared library. For more information, see Plug-In Register Functions
2. Write C language plug-in register functions that include: the initiating function, the exiting function, the vtable setting function, and the information providing function if necessary. These register functions need to be exported so that they can be invoked from the GWWS server. For more information, see Plug-In Register Functions
3. Compile all the above functions into one shared library.
