SDK: Set keyframes of effect parameters

Hey

I'm working on a c++ effect for After Effects. When the effect is added to the layer, one of the parameters should already have two keyframes. What would be the best way to do that? My idea was to put the code in the GlobalSetup function. I do realise that if that works I will probably need an if statement checking if it is already keyframed.

My problem is simply how to write a keyframe to the effects parameter. I feel close but I'm not sure how to actually set the desired value. I have this:

static PF_Err 
GlobalSetup (	
	PF_InData		*in_data,
	PF_OutData		*out_data,
	PF_ParamDef		*params[],
	PF_LayerDef		*output )
{
	PF_Err 					err 		= PF_Err_NONE;
	
	PF_Handle				globH		= NULL;
	my_global_dataP			globP		= NULL;
	AEGP_PluginID			pluginID;
	AEGP_StreamRefH			streamH = NULL;
	AEGP_AddKeyframesInfoH	akH = NULL;
	AEGP_EffectRefH			effectPH = NULL;
	A_long					indexPL = NULL;
	AEGP_StreamValue2		valueP;

	AEGP_SuiteHandler		suites(in_data->pica_basicP);

	out_data->my_version = PF_VERSION(	MAJOR_VERSION, 
										MINOR_VERSION,	
										BUG_VERSION, 
										STAGE_VERSION, 
										BUILD_VERSION);

	out_data->out_flags = PF_OutFlag_PIX_INDEPENDENT |
								PF_OutFlag_SEND_UPDATE_PARAMS_UI	|
								PF_OutFlag_USE_OUTPUT_EXTENT		|
								PF_OutFlag_DEEP_COLOR_AWARE			|
								PF_OutFlag_WIDE_TIME_INPUT;
	
	out_data->out_flags2 = PF_OutFlag2_PARAM_GROUP_START_COLLAPSED_FLAG |
								PF_OutFlag2_DOESNT_NEED_EMPTY_PIXELS	|
								PF_OutFlag2_AUTOMATIC_WIDE_TIME_INPUT	|
								PF_OutFlag2_SUPPORTS_THREADED_RENDERING;

	globH	=	suites.HandleSuite1()->host_new_handle(sizeof(my_global_data));
	
	if (globH) {
		globP = reinterpret_cast<my_global_dataP>(suites.HandleSuite1()->host_lock_handle(globH));
		if (globP) {
			globP->initializedB 	= TRUE;

			if (in_data->appl_id != 'PrMr') {
				ERR(suites.UtilitySuite3()->AEGP_RegisterWithAEGP(NULL, STR(StrID_Name), &globP->my_id));
			}
				if (!err){
					out_data->global_data 	= globH;
			}
		}
		suites.HandleSuite1()->host_unlock_handle(globH);
	} else	{
		err = PF_Err_INTERNAL_STRUCT_DAMAGED;
	}

	const A_char* pluginName = STR(StrID_Name);
	ERR(suites.UtilitySuite5()->AEGP_RegisterWithAEGP(NULL, pluginName, &pluginID));

	ERR(suites.PFInterfaceSuite1()->AEGP_GetNewEffectForEffect(pluginID, in_data->effect_ref, &effectPH));

	ERR(suites.StreamSuite5()->AEGP_GetNewEffectStreamByIndex(pluginID, effectPH, 25, &streamH));
	
	ERR(suites.KeyframeSuite4()->AEGP_StartAddKeyframes(streamH, &akH));
	
	ERR(suites.KeyframeSuite4()->AEGP_AddKeyframes(akH, AEGP_LTimeMode_CompTime, 0, &indexPL));

	valueP.one_d = 20; // How do I set the value?
	
	ERR(suites.KeyframeSuite4()->AEGP_SetAddKeyframe(akH, indexPL, &valueP));
	
	ERR(suites.StreamSuite3()->AEGP_DisposeStreamValue(&valueP));

	AEFX_CLR_STRUCT(valueP);

	ERR(suites.KeyframeSuite4()->AEGP_EndAddKeyframes(true, akH));

	ERR(suites.StreamSuite2()->AEGP_DisposeStream(streamH));
	ERR(suites.EffectSuite2()->AEGP_DisposeEffect(effectPH));

	return err;
}

I get this error: class "AEGP_StreamValue2" has no member "one_d.
Any help will be greatly appreciated. 

Thanks,
