pars_user_func_t* fetch_node_t::func

User callback function or NULL. The first argument to the function is a sel_node_t*, containing the results of the SELECT operation for one row. If the function returns NULL, it is not interested in further rows and the cursor is modified so (cursor % NOTFOUND) is true. If it returns not-NULL, continue normally. See row_fetch_print() for an example (and a useful debugging tool).
