See PL/R for examples:
http://www.joeconway.com/plr/
Specifically:
plr.c:do_compile()
gathering required information for input conversion of return values
pg_conversion.c:get_scalar_datum()
conversion from (char *value) to Datum using the gathered info for
scalar return datums
pg_conversion.c:get_generic_array_datum()
conversion from multiple (char *values) to Datum using the gathered
info for array return datums
