This function is optional. If it is used, it is first invoked after the plug-in shared library is loaded during GWWS server startup. If you want to implement more than one interface in one plug-in library, you must implement this function and return the counts, IDs, and names of the interfaces in the library.

Returning a 0 value indicates the function has executed successfully. Returning a value other than 0 indicates failure. If this functions fails, the plug-in is not loaded, and the GWWS server will not start.

The function uses the following syntax:

int _ws_pi_get_Id_and_Names(int * count, char **ids, char **names);

You must return the total count of implementation in the library in arguments count. The arguments ids andnamesshould contain all implemented interface ids and names, separated by a semicolon “;”.
