AP_EventCodecCtorPtr
 
/**
* Pointer to the constructor function for the codec library. Each codec
* plugin library must export a function with this signature, named using
* the AP_EVENTCODEC_CTOR_FUNCTION_NAME macro.
*
* Constructs a new instance of the event codec. This function will be
* called by the adapter main program when the adapter starts up.
*
* Note that the input parameters (name, properties, timestampConfig) are
* owned by the caller. The IAF framework guarantees that properties and
* timestampConfig will remain valid until after a subsequent call to
* updateProperties(), so it is safe to hold a pointer to this structure.
* You should, however, copy the name string if you wish to keep it. The
* contents of the output parameter errMsg belongs to the codec.
*
* @param name The name of this codec instance, also found in properties
* @param properties Codec property set derived from the IAF config file
* @param err 'Out' parameter for error code if constructor fails
* @param errMsg 'Out' parameter for error message if constructor fails
* @param timestampConfig Timestamp recording/logging settings
* @return Pointer to a new codec instance or NULL if the constructor fails
* for some reason. In the case of failure, err and errMsg should be filled
* in with an appropriate error code and message describing the failure.

* bidirectional codecs.
*
* @param version 'Out' parameter for version number of codec library. This
* should be the value of AP_EVENTCODEC_VERSION that was defined in
* EventCodec.h when the codec was built. The IAF will check the version
* number to ensure that it can support all the capabilities offered by the
* codec.
* @param capabilities 'Out' parameter for the capabilities of the codecs
* provided by this library. This should be the sum of the appropriate
* AP_EVENTCODEC_CAP_* constants found in EventCodec.h.
