Porting Application Programs

CPI-C

Chapter 3 37

CPI-C

No action is necessary to migrate a CPI-C (Common Programming

Interface Communications) application; the application can run

unchanged with the new shared libraries. However, if the application

uses the Terminate_Application function, see “Terminate_Application

Function”, for further information.

Terminate_Application Function

The CPI-C Terminate_Application function is no longer required by

any SNAplus2 CPI-C application. This function was originally added to

SNAplus CPI-C to overcome a limitation in the CPI-C interface, which

restricted the application to only one Accept_Conversation call, but

this limitation has now been removed

The current version of SNAplus2 supports Terminate_Application, so

existing CPI-C applications that use this function can be used without

source code modiﬁcations. However, the function will not be supported in

future versions of SNAplus2. Begin removing this function from existing

applications now, to ensure that they continue to work with later

SNAplus2 versions.
