Callbacks cannot be implemented for programming language and platform combinations that do not support function calls by pointer reference. If this is the case, an application:
Must handle Client-Library and server messages inline, using ct_diag.
Still uses ct_poll to check for a completion or notification callback event, but must directly call any routine handling the event.
To determine whether callbacks are supported for a programming language and platform version of Client-Library, use the Open Client and Open Server Programmers Supplement for Microsoft Windows or Open Client and Open Server Programmers Supplement for UNIX.
