1102 /* This group of functions allows a caller to evaluate an expression from
1103 the callee's interface. It establishes a mapping between the interface's
1104 dummy arguments and the caller's actual arguments, then applies that
1105 mapping to a given gfc_expr.
1107 You can initialize a mapping structure like so:
1109 gfc_interface_mapping mapping;
1111 gfc_init_interface_mapping (&mapping);
1113 You should then evaluate each actual argument into a temporary
1114 gfc_se structure, here called "se", and map the result to the
1115 dummy argument's symbol, here called "sym":
1117 gfc_add_interface_mapping (&mapping, sym, &se);
1119 After adding all mappings, you should call:
1121 gfc_finish_interface_mapping (&mapping, pre, post);
1123 where "pre" and "post" are statement blocks for initialization
1124 and finalization code respectively. You can then evaluate an
1125 interface expression "expr" as follows:
1127 gfc_apply_interface_mapping (&mapping, se, expr);
1129 Once you've evaluated all expressions, you should free
1130 the mapping structure with:
1132 gfc_free_interface_mapping (&mapping); */
