814 | /* This group of functions allows a caller to evaluate an expression from | |
815 | the callee's interface. It establishes a mapping between the interface's | |
816 | dummy arguments and the caller's actual arguments, then applies that | |
817 | mapping to a given gfc_expr. | |
818 | ||
819 | You can initialize a mapping structure like so: | |
820 | ||
821 | gfc_interface_mapping mapping; | |
822 | ... | |
823 | gfc_init_interface_mapping (&mapping); | |
824 | ||
825 | You should then evaluate each actual argument into a temporary | |
826 | gfc_se structure, here called "se", and map the result to the | |
827 | dummy argument's symbol, here called "sym": | |
828 | ||
829 | gfc_add_interface_mapping (&mapping, sym, &se); | |
830 | ||
831 | After adding all mappings, you should call: | |
832 | ||
833 | gfc_finish_interface_mapping (&mapping, pre, post); | |
834 | ||
835 | where "pre" and "post" are statement blocks for initialization | |
836 | and finalization code respectively. You can then evaluate an | |
837 | interface expression "expr" as follows: | |
838 | ||
839 | gfc_apply_interface_mapping (&mapping, se, expr); | |
840 | ||
841 | Once you've evaluated all expressions, you should free | |
842 | the mapping structure with: | |
843 | ||
844 | gfc_free_interface_mapping (&mapping); */ | |
