It's "dissect_ndr_uint32".

In that particular case, if you declare a variable

	guint32 inquiry_type;

in that routine, and call

	offset = dissect_ndr_uint32 (tvb, offset, pinfo, tree, drep,
                                 hf_epm_inquiry_type, &inquiry_type);

then "dissect_ndr_uint32()" will return the value of that field in the
"inquiry_type" variable - you wouldn't have to fetch it yourself with a
"tvb_get_xxx" routine.

So, after that, you'd use a "col_add_fstr()" call to display the value
in the Info column.
