Hello Timothy: this is a C function: LONG WINAPI HSM_GenWKByMK( HSMHANDLE Handle, int Encmod, int * KeyLen, unsigned char * SymKeyByMK ); the SymKeyByMK is a output param,in JAVA I mapped that byte[],but I can't get the out param,Is there something wrong with my mapping? Thanks for your time.

NativeLong HSM_GenWKByMK(Pointer handle, int encmod, IntByReference keylen, byte[] SymKeyByMK)

Just make sure your byte array is large enough to handle the output, and that your library implements StdCallLibrary.
