Yes, this is the Scheme interface to the C function using the FFI.
pgscsh already uses this for MD5 authentication when running under
Scsh.  AFAIK this approach doesn't play nice with threads; all threads
in the process block until the C call return.  For Scheme 48 (and for
Scsh too, eventually) I think it would be better to port PLT's version
of the MD5 library, which is written in Scheme only.
