Eliminating LE usage from a [non-Metal] C function would be a formidable undertaking. You can, however, set up the LE before the first CALL to your C function and keep it up between these CALLs in such a way that you incur the setup overhead only once.
As is often the case, the LE Vendor Interfaces manual contains relevant information even for non-vendors.
