sa_send_udp( 
destAddress, 
destPort, 
msg 
)

This procedure sends a single UDP packet to the specified address. The procedure returns 0 if the message is sent successfully, and returns an error code if an error occurs. The error code is one of the following:

If the msg parameter contains binary data or is more complex than a string, you may want to use a variable. For example,

CREATE VARIABLE v LONG BINARY;
SET v='This is a UDP message';
SELECT dbo.sa_send_udp( '10.25.99.124', 1234, v );
DROP VARIABLE v;

This procedure can be used with MobiLink server-initiated synchronization to wake up the Listener utility (dblsn.exe). If you use the sa_send_udp system procedure as a way to notify the Listener, you should append a 1 to your UDP packet. This number is a server-initiated synchronization protocol number. In future versions of MobiLink, new protocol versions may cause the Listener to behave differently.

The following example sends the message "This is a test" to IP address 10.25.99.196 on port 2345:

CALL sa_send_udp( '10.25.99.196', 2345', 'This is a test' );
