It would be nice if one doesn't need to write wrappers and the APL system can do the structure conversions within the APL interpreter. In J, you can dlopen a library and pass J values directly without writing and compiling C, see
http://www.jsoftware.com/help/user/call_procedure.htm and the relevant code is at https://github.com/jsoftware/jsource/blob/master/jsrc/x15.c It would simplify using external libraries a lot. > On Feb 4, 2017, at 7:38 AM, Juergen Sauermann <juergen.sauerm...@t-online.de> > wrote: > > Hi, > > yes there is: native functions.
