Parameter Interpolation Type about openfx HOT 3 OPEN

Would this be requesting a default interpolation type for the parameter instead of just getting whatever the host decides? Or do you want to set specific key values and interpolation types as part of the default value?
Can you provide concrete examples of how this would be used?

This needs further discussion. I believe Pierre's example is he wants to do some analysis which then sets some keyframes, and instead of getting the default host linear or smooth interpolation he wants to indicate that the keys should be step-evaluated (ie. kOfxParamInterpTypeConstantStep or kOfxParamInterpTypeHold).

How about something like this?

enum OfxParamInterpType {
   kOfxParamInterpTypeConstantStep,   // hold until next key
   kOfxParamInterpTypeLinear,     // linear
   kOfxParamInterpTypeSmooth,  // some type of smooth curve
   kOfxParamInterpTypeCustom   // get-only, since this could be host-specific
};

typedef struct OfxParameterSuiteV2 {
   // ... same stuff as in V1
     OfxStatus (*paramGetInterpType)(OfxParamHandle  paramHandle,
			       unsigned int nthKey,
			       int *type);
     OfxStatus (*paramSetInterpType)(OfxParamHandle  paramHandle,
			       unsigned int nthKey,
			       int type);
};
