+.Sh DESCRIPTION
+These functions retrieve the offsets, relative to the
+.Dq ".debug_info"
+DWARF section, of the debugging information entries describing the
+compilation unit associated with a
+.Vt Dwarf_Arange
+descriptor.
+.Pp
+Function
+.Fn dwarf_get_arange_cu_header_offset
+retrieves the offset of the compilation unit header associated with
+argument
+.Ar ar ,
+and stores it in the location pointed to by argument
+.Ar ret .
+.Pp
+Function
+.Fn dwarf_get_cu_die_offset
+retrieves the offset of the debugging information entry for the
+compilation unit associated with argument
+.Ar ar ,
+and stores it in the location pointed to by argument
+.Ar ret .
+.Pp
+If argument
+.Ar err
+is not NULL, these functions will use it to store error information,
+in case of an error.
+.Sh RETURN VALUES
+On success, these functions returns
+.Dv DW_DLV_OK .
+In case of an error, they return
+.Dv DW_DLV_ERROR
+and set the argument
+.Ar err .
+.Sh ERRORS
+These functions may fail with:
+.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
+.It Bq Er DW_DLE_ARGUMENT
+Argument
+.Ar ar
+was not a valid
+.Vt Dwarf_Arange
+descriptor.
+.It Bq Er DW_DLE_ARGUMENT
+Argument
+.Ar ret
+was NULL.
