Problem about Bytea and SQL_C_CHAR

Hi,
    Here is the code:

    strcpy(data, "FF");
    cb = 2;
    rc = SQLBindParameter(hstmt, i,
                        SQL_PARAM_INPUT,
                        SQL_C_CHAR, SQL_VARBINARY,
                        precision, scale,
                        &data, MAX_STRING_SIZE,
                        &cb);
    rc = SQLPrepare(hstmt, "insert into test(ColBytea) values(?)", SQL_NTS);
    rc = SQLExecute(hstmt);

    After this, the value inserted in column ColByteatable(datatype is bytea) of table test was a char string 'FF',
whichwas expected to be 0xFF(255). 

    There's no problem with binary column in Ms Sql Server. I'm porting my code from sql server to postgresql. So help
me,please! 

    Regards!
