Indicator Functions (Row-Based Mode)

Use the indicator functions when you want the procedure to get the indicator for an input port or to set the indicator for an output port. The indicator for a port indicates whether the data is valid, null, or truncated.

CDI-PC

provides the following indicator functions:

INFA_CTGetIndicator().
Gets the indicator for an input port. Use the following syntax:

INFA_INDICATOR INFA_CTGetIndicator(INFA_CT_INPUTPORT_HANDLE dataHandle);

The return value datatype is INFA_INDICATOR. Use the following values for INFA_INDICATOR:

INFA_DATA_VALID.
Indicates the data is valid.

INFA_NULL_DATA.
Indicates a null value.

INFA_DATA_TRUNCATED.
Indicates the data has been truncated.

INFA_CTSetIndicator().
Sets the indicator for an output port. Use the following syntax:

INFA_STATUS INFA_CTSetIndicator(INFA_CT_OUTPUTPORT_HANDLE dataHandle, INFA_INDICATOR indicator);

The following table describes the arguments for this function:

Argument	Datatype	Input/Output	Description
dataHandle	INFA_CT_OUTPUTPORT_HANDLE	Input	Output port handle.
indicator	INFA_INDICATOR	Input	The indicator value for the output port. Use one of the following values: INFA_DATA_VALID. Indicates the data is valid. INFA_NULL_DATA. Indicates a null value. INFA_DATA_TRUNCATED. Indicates the data has been truncated.

The return value datatype is INFA_STATUS. Use INFA_SUCCESS and INFA_FAILURE for the return value.

If you use the INFA_CTSetPassThruPort() function on an input/output port, do not set the data or indicator for that port.
