This function attaches to the point using the pointname parameter as the identifier.
Result = EOS_PT_ATTACH(fid, pointname)
Returns the point handle (pointID) if successful and FAIL (-1) otherwise.Typical reasons for failure are an improper point file id or point name.
Point file id (long) returned by EOS_PT_OPEN.
Name of point (string) to be attached.
In this example, we attach to the previously created point, "ExamplePoint", within the HDF file, PointFile.hdf, referred to by the handle, fid:
pointID = EOS_PT_ATTACH(fid, "ExamplePoint")
The point can then be referenced by subsequent routines using the handle, pointID.
