define external function TCPConnectionPut
value TCPConnection this-TCPConnection
from value stream characters-to-be-put
timeout value counter timeout-in-milliseconds optional
as TCPConnectionPut
This function writes characters to a TCP connection, sending them to the receiver.
TCPConnectionPut can be formulated in terms of TCPConnectionGetOutput as follows:
define function TCPConnectionPut
value TCPConnection this-TCPConnection
from value stream characters-to-be-put
timeout value counter timeout-in-milliseconds optional
as
do when timeout-in-milliseconds is specified
set TCPConnectionGetOutput this-TCPConnection
timeout timeout-in-milliseconds
to characters-to-be-put
else
set TCPConnectionGetOutput this-TCPConnection
to characters-to-be-put
done
The difficulties inherent with multiple derived outputs apply to uses of TCPConnectionPut also. That is, only one external output from a connection can be derived (active) at any one time. The current external output must be closed before you can issue a TCPConnectionPut.
Note that sequential uses of TCPConnectionPut in the absence of any use of TCPConnectionGetOutput is allowed.
Any attempt to do a TCPConnectionPut when there is already active output derived from TCPConnectionGetOutput output is not allowed and will result in an OmniMark external function exception.
Any attempt to do a TCPConnectionPut when the associated TCP connection has been closed using TCPConnectionClose is in error, in the same manner as for an external output derived from the TCP connection.
Arguments:
Example:
local TCPConnection TCP-Conn
set TCP-Conn to TCPConnectionOpen on "localhost" at 5300
TCPConnectionPut TCP-Conn from "hello world"
TCPConnectionPut TCP-Conn from ((("*" ||* 78) || "%n") ||* 40)
