);

[C++]
Parameters
pSR 
  pSR is a parameter of type ISpatialReference
pG1 
  pG1 is a parameter of type IGeometry
pG2 
  pG2 is a parameter of type IGeometry
pDistanceUnit

Remarks

The distance value is computed in the specified linear units, if present, or in the units of the spatial reference. If SpatialReference is a projected coordinate system, the input geometries will first be inverse projected and then shortest geodesic distance will be computed on the latitude-longitude coordinates.
