Subject: [Rd]  R_CallMethodDef: 'type' and 'style' fields?
Message-ID: <25803313.post@talk.nabble.com>


In Writing R Extensions it is said that R_CallMethodDef has two optional
fields, 'type' and 'style' (where 'style' is said to distinguish
in/out/inout arguments). But it doesn't give the possible values for
'style'. Looking at the header Rdynload.h (version 2.9.2) it appears that
R_CallMethodDef  does not have these extra two fields. 

Were they removed at some point? If so, what is the best way to call a C
function without the overhead of copying the inputs?

Thanks
