3.3. Error Handling

When the Caller ID function completes, check the return code.

• If the Caller ID function completes successfully, the buffer contains the Caller ID information.
• If the Caller ID function completes unsuccessfully, an error code is returned that indicates the reason for the error.
• When using the dx_gtextcallid( ), error codes depend upon the Message Type ID argument (infotype) passed to the function. All Message Types can produce an EDX_CLIDINFO error. Message Type CLIDINFO_CALLID can also produce EDX_CLIDOOA and EDX_CLIDBLK errors.

NOTE:

The call is still active when an error is returned for a Caller ID function.

When using the dx_gtcallid( ) Caller ID function, if an error is returned indicating the caller's phone number (DN) is blocked or out of area, other information such as date and time may be available by issuing the dx_gtextcallid( ) Caller ID function. The information available, other than the caller's phone number, is determined by the CO.
