◆ getname_anim_fcurve()

std::optional< int > getname_anim_fcurve	(	char *	name,
		ID *	id,
		FCurve *	fcu )

Get icon + name for channel-list displays for F-Curve.

Write into "name" buffer, the name of the property (retrieved using RNA from the curve's settings), and return the icon used for the struct that this property refers to

Warning: name buffer we're writing to cannot exceed 256 chars (check anim_channels_defines.cc for details).

Returns: the icon of whatever struct the F-Curve's RNA path resolves to. Returns #std::nullopt if the path could not be resolved.

◆ getname_anim_fcurve_for_slot()

std::string getname_anim_fcurve_for_slot	(	Main &	bmain,
		const blender::animrig::Slot &	slot,
		FCurve &	fcurve )

Get the name of an F-Curve that's animating a specific slot.

This function iterates the Slot's users to find an ID that allows it to resolve its RNA path.
