A C/C++ transport layer plug-in is implemented as a dynamic shared library. In order for the IAF to be able to load and use it, it must comply with Apama's transport plug-in development specification. This specification describes the structure of a transport layer plug-in, and the C/C++ functions it needs to implement so that it can be used with the IAF. The specification also provides a mechanism for startup and configuration parameters to be passed to the plug-in from the IAF's configuration file.

Property names and values used by transport plug-ins must be in UTF-8 format.

A transport layer plug-in implementation must include the C header file EventTransport.h. It also needs to include EventCodec.h, to allow the event transport to pass messages to codecs within the IAF codec layer. You can find these files in the include directory of your Apama installation.
