xPCCloseConnection - Close RS-232 or TCP/IP communication connection
Prototype
void xPCCloseConnection(int port);
Arguments
port | Enter the value returned by either the function xPCOpenSerialPort or the function xPCOpenTcpIpPort. |
Description
The xPCCloseConnection function closes the
RS-232 or TCP/IP communication channel opened by xPCOpenSerialPort, xPCOpenTcpIpPort, or xPCOpenConnection. Unlike xPCClosePort, it preserves
the connection information such that a subsequent call to xPCOpenConnection succeeds without the need to resupply communication
data such as the IP address or port number. To completely close the
communication channel, call xPCDeRegisterTarget. Calling
the xPCCloseConnection function followed by calling xPCDeRegisterTarget is equivalent to calling xPCClosePort.
