 Close Session
Applications can call this function to close its session with the VDD.
An application should call this function before it terminates if a session
was earlier established with the VDD. The reason for this is to ensure
that all created MSMQ queues for the client are deleted. This will
prevent irrelevant/outdated messages from being posted to inactive
MSMQ queues.
Prototype:
int VDDClose(void);
Description:
Close a session with the VDD.
Input:
 None
Output:
 Return value = 0 Operation was successful
 Return value ≠ 0 Operation failed. Value specifies the error type
 Send Data to a Radio Host
Applications can call this function to send data to a radio host. The
Host ID will automatically be inserted into the data header of the SDU
for message routing purposes.
Prototype:
int nclSendData(word *usSduTag, byte *szHostId, byte ucIdLen, byte
*ucData, int iDatLen, bool bResend);
Response:
The VDD will track the response with the Host ID and SDU tag will
post the response to the corresponding RX queue for that session. The
application is responsible for reading and processing the response on
the RX queue. By calling ‘nclReceiveData()’.
Description:
Send application data to the radio host identified by the host ID.
