| Platform SDK: TAPI |
Application-specific information allows applications to pass each other information concerning a session through TAPI. This information is not interpreted by TAPI and usage is entirely defined by the applications.
When application-specific information is changed by one application, TAPI sends all other applications with monitor or owner privileges on the session an event indicating that a change has occurred.
Not all service providers support use of this information.
