int ctDECL ctPlugin_describe(char * name,size_t * size,int request)
ctPlugin_describe() is called at startup and must handle several values of "request": ctPlugin_describe() defines a set of additional user callback functions contained in a server side shared library that should be loaded at server startup. It is intended for use in implementing server side PlugIns. These additional functions are not called directly, but can be invoked by existing callback functionality such as Record Update Callbacks.
Return value should be zero on success or non-zero on error.
