Error while connecting to oracle 10g data base

Question

Following is the code we used to connect to oracle 10g data base using symbian 7.1 series 80 SDK
int CTest_S80AppUi::SetupODBC(void)
RETCODE rc;
char *DataSource = OD_DATA_SOURCE;
char UserId = "system", Password = "manager";
rc=SQLAllocEnv(&Henv);
//if (TEST_CHECK_ERR(SQL_NULL_HSTMT, rc, "SQLAllocEnv", FALSE) < 0) return(-1);
rc=SQLAllocConnect(Henv, &Hdbc);
//if (TEST_CHECK_ERR(SQL_NULL_HSTMT, rc, "SQLAllocConnect", FALSE) < 0)
     //return(-1);
rc = SQLConnect(Hdbc, (unsigned char *)DataSource, SQL_NTS,
          (unsigned char *)UserId, SQL_NTS,
          (unsigned char *)Password, SQL_NTS);
bConnected = TRUE;
//if (TEST_CHECK_ERR(SQL_NULL_HSTMT, rc, "SQLConnect", FALSE) < 0) return(-1);
SQLAllocStmt(Hdbc, &Hstmt);
//if (TEST_CHECK_ERR(SQL_NULL_HSTMT, rc, "SQLAllocStmt", FALSE) < 0) return(-1);
return (1);
} /* SetupODBC */
iam getting the return code for SQLConnect as -1.
Thanks in advance.

Thanks for the reply.
//syntax means comments.
chk the following code.
int SetupODBC(void)
char *DataSource = "polite";
char UserId = "system", Password = "manager";
if ( SQLAllocEnv(&Henv) < 0 )
return -1;
if ( SQLAllocConnect(Henv, &Hdbc) < 0 )
return -1;
if ( SQLConnect(Hdbc, (unsigned char *)DataSource, SQL_NTS,
(unsigned char *)UserId, SQL_NTS,
(unsigned char *)Password, SQL_NTS) < 0 )
return -1;
if (SQLAllocStmt(Hdbc, &Hstmt) < 0 )
return -1;
return (0);
As said earlier there is a problem in SQLConnect. It is returning -1.
But the code should return 0 if successfully connected.
The info regarding the arguments used in the above methods:
HENV Henv; /* Handle to ODBC Environment object */
HDBC Hdbc; /* Handle to ODBC Connection object */
HSTMT Hstmt; /* Handle to ODBC Statement object */
