float <name>; => c_float <name>;
double <name>; => c_double <name>;
boolean <name>; => c_bool <name>;

* If the type specification is a user defined idl_ttypedef, idl_tenum,
* idl_tstruct or idl_tunion a scoped name mapping will be generated.
* @verbatim

* with the array specifiers:

sequence<spec,length> <name>; => c_sequence <name,length>;
@endverbatim
*
* @param scope Current scope
* @param name Name of the structure member
