For example, to test if the socket is connected:

STATUS% = GETSOCKOPT%( SN%, 0800h, OPTION_VALUE%)

8.12 SHUTDOWN% Function

Format:

SHUTDOWN%(

sn% )

where:

sn% is the number of the socket for which the

connection should be terminated.

This function closes the socket to allow it to be reused at a later

time.

TCP sockets need to be shut down at only one end. Either the active

or passive side may close the connection. The other side will

automatically shut down. UDP and Raw Ethernet sockets need to be

shut down at both ends.

Values Returned:

ă1 Success

-2 ENI not initialized

-15 Bad socket number

-28 Socket closed by destination

For example:

STATUS% = SHUTDOWN%( SOCKET_NUM% )
