Hi,

I am trying to call a C function from PL/SQL and I encounter "ORA-06525 Length Mismatch for CHAR or RAW data". Following is the information:

C function in util.dll:
INT Scramble(BYTE *input,

	 BYTE *key, 
	 INT which,
	 BYTE *output);

I create the library and PL/SQL body using the following script: CREATE OR REPLACE LIBRARY util
AS

   'E:\Develop\test\util.dll';

CREATE OR REPLACE FUNCTION Scramble

	(plaintext IN RAW,
	key IN RAW,
	which IN PLS_INTEGER,
	ciphertext IN OUT RAW)

   RETURN PLS_INTEGER
   IS EXTERNAL

      LIBRARY util
      NAME "Scramble"
      LANGUAGE C;

When I test the above function Scramble using the following PL/SQL, I receive the error at the beginning of this message.

DECLARE
   rvalue PLS_INTEGER;

   plaintext 	RAW(8);
   key		RAW(16);
   which	PLS_INTEGER;
   ciphertext	RAW(8);
BEGIN
	plaintext := '12345678';
	key	:= '1234567812345678';
	which	:= 0;
	

• SQL error at the following line!!!!!
• "ORA-06525 Length Mismatch for CHAR or RAW data" rvalue := SCRAMBLE(plaintext, key, which, ciphertext); END;

Could anyone give me any idea what's wrong with the above code. Thank you.

Cheers,
