emedded SQL in C to get the record type from plpgsql

So how can emedded SQL in C to get the record type which returning from plpgsql function?

I have tested as following code:

CREATE OR REPLACE FUNCTION test4(IN a integer, OUT b int,OUT c int) AS $BODY$ declare begin b:=100; c:=200; return; END $BODY$

  LANGUAGE 'plpgsql' VOLATILE

  COST 100;

// imbedded SQL in C

int test(int a)

{

EXEC SQL TYPE my_type IS STRUCT

{

int b[1];

int c[1];

};

EXEC SQL BEGIN DECLARE SECTION;

my_type ppp;

EXEC SQL END DECLARE SECTION;

EXEC SQL WHENEVER sqlerror SQLPRINT;

EXEC SQL select  test4(1) into :ppp;

EXEC SQL COMMIT;

return 0;

}

Running binary cause error:

SQL error: invalid input syntax for type int: "(100,200)",

My project is migrating from Oracle to postgresql,can you help me ?
