Hello, I'm writing a SRF following the example from http://www.postgresql.org/docs/8.4/interactive/xfunc-c.html (section 34.9.10). In the example, in the code executed in first call, we get the number of tuples to be returned, and no more. Then, in each call, a new tuple is allocated and returned, until reach max_calls. My problem is I want to return an array of structs, and that array is returned (as a pointer) by an external function. I can call that funcion in first call, and then store a the returned array in funcctx->user_fctx. In successive calls, I can get one new element of the array pointed by user_fctx, but I'd need the number of elements (the classical problem "how to get the number of elements of a dinamically allocated array"). Would the best way to modify the external function to get, somehow, the number of structs returned? Is there any better way to do what I need? Thanks in advance, and best regards Jorge ---- http://www.gis4free.org/blog -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
