You can clone the code for d-GetType. Starting in view.c you find

install_scm_function (DENEMO_SCHEME_PREFIX"GetType",  scheme_get_type);

and

SCM scheme_get_type (SCM optional) {  clone the code to return a string
for the clef }

which are all you need to clone. 

The problems will arise in understanding what Denemo stores for clefs -
there is the leftmost clef and, I think, something for the initial clef:
I think there may well be a serious bug in there - if the leftmost clef
is not the prevailing one or if the prevailing one is not the initial
one or something - I am waiting for a user to nail it down, or at least
report it. As it is, I don't know if you can tell what the clef is at
the current cursor position. (I've been overly pessimistic before, just
because I didn't understand what all the fields mean, so I may be
wrong).
