Обсуждение: Constructing array

Hi!

Does anybody have a good pointer for an example of how to construct an 
array in a SRF? Or if not such a pointer, hints on which way is best to 
do it? (it'll be an array of text strings, one-dimensional)

(This is from C, if that's not obvious)

If you can build it in one swoop, use construct_array().  If you need
to build it incrementally then things will be much more painful...

I'm sure there are other good examples, but one possibility is to look 
at pg_conversion.c in PL/R source. Start with get_array_datum().
