GetTrackEnvelopeByName()
TrackEnvelope* GetTrackEnvelopeByName(MediaTrack* track, const char* envname)
This function returns an opaque pointer to a track envelope. To use this pointer it must be passed to a function such as GetSetEnvelopeState() which allows you to Get or Set the contents of an envelope.
Envelope names can be found in a project's .rpp file.

Returns
TrackEnvelope* - an opaque pointer to a track envelope
Examples
C++
Perl
Python
""" The pointer returned by RPR_GetTrackEnvelopeByName() can't be accessed directly. Instead, you need to call RPR_GetSetEnvelopeState(), which returns a text representation similar to the RPP file. Changes to the envelope data are made by calling RPR_GetSetEnvelopeState() with the changed envelope data.
