Regular API function

Description	Retrieves interpolated user data along a path object. See also simGetPositionOnPath, simGetOrientationOnPath, simGetPathPosition and simGetClosestPositionOnPath.
C synopsis	simInt simGetDataOnPath(simInt pathHandle,simFloat relativeDistance,simInt dataType,simInt* intData,simFloat* floatData)
C parameters	pathHandle: handle of the path object relativeDistance: a value between 0 and 1, where 0 is the beginning of the path, and 1 the end of the path. Make sure you selected the appropriate path length calculation method. See also simGetPathLength. In order to retrieve data that lies exactly on a specific path control point, specify following for relativeDistance: -ctrlPtIndex-1 (the value will be rounded appropriately). dataType: the type of the desired data. Keep 0. intData: pointer to a one-dimensional array that will receive the auxiliary flags value at the given path relative distance. floatData: pointer to a 4-dimensional array that will receive the auxiliary channel values at the given path relative distance.
C return value	-1 if operation was not successful. In a future release, a more differentiated return value might be available
Lua synopsis	number auxFlags,table_4 auxChannels=simGetDataOnPath(number pathHandle,number relativeDistance)
Lua parameters	Same as C-function
Lua return values	Similar as C-function
