Sends the message “Hello” to port 3456 at IP address 120.10.20.5:
select syb_sendmsg("120.10.20.5", 3456, "Hello")
Reads the IP address and port number from a user table, and uses a variable for the message to be sent:
declare @msg varchar(255) select @msg = "Message to send" select syb_sendmsg (ip_address, portnum, @msg) from sendports where username = user_name()
To enable the use of UDP messaging, a System Security Officer must set the configuration parameter allow sendmsg to 1.
No security checks are performed with syb_sendmsg. Sybase strongly recommends caution when using syb_sendmsg to send sensitive information across the network. By enabling this functionality, the user accepts any security problems which result from its use.
For a sample C program that creates a UDP port, see sp_sendmsg.
