Callbacks

Callbacks are not always supported

Callbacks are not always supported

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.

Use the Open Client/Server Programmer's Supplement for your platform to determine whether callbacks are supported for a programming language and platform version of Client-Library.
