Re: AEGP_LayerH from a PF_Param_LAYER?

Wow:

PF_Err get_layer_handle(PF_InData *in_data, AEGP_LayerH *layer_handle)

{

    AEGP_SuiteHandler suites(in_data->pica_basicP);

    PF_Err err = PF_Err_NONE;

    AEGP_EffectRefH  effect_handle = NULL;

    ERR(suites.PFInterfaceSuite1()->AEGP_GetNewEffectForEffect(plugin_id, in_data->effect_ref, &effect_handle));

    AEGP_StreamRefH stream_handle = NULL;

    ERR(suites.StreamSuite2()->AEGP_GetNewEffectStreamByIndex(CG_FRAME_DATA_LAYER, effect_handle, CG_FRAME_DATA_LAYER, &stream_handle));

    AEGP_LayerIDVal layer_id;

    {

        // Layer effects can't be keyframed, so the timestamp doesn't matter.

        A_Time timeT = {0,1};

        AEGP_StreamValue value;

        ERR(suites.StreamSuite2()->AEGP_GetNewStreamValue(plugin_id, stream_handle, AEGP_LTimeMode_LayerTime, &timeT, TRUE, &value));

        layer_id = value.val.layer_id;

        ERR(suites.StreamSuite2()->AEGP_DisposeStreamValue(&value));

    }

    AEGP_LayerH effect_layer_handle = NULL;

    ERR(suites.PFInterfaceSuite1()->AEGP_GetEffectLayer(in_data->effect_ref, &effect_layer_handle));

    AEGP_CompH comp_handle = NULL;

    ERR(suites.LayerSuite5()->AEGP_GetLayerParentComp(effect_layer_handle, &comp_handle));

    ERR(suites.LayerSuite8()->AEGP_GetLayerFromLayerID(comp_handle, layer_id, layer_handle));

    if(effect_handle != NULL)

        ERR(suites.EffectSuite2()->AEGP_DisposeEffect(effect_handle));

    return err;

}

I hope there's a simpler way to do something this basic.  The SDK documentation needs a major overhaul; I was only able to get this to work by combining several of the (not very cleanly-written) examples and a huge amount of web searching.
