#include <isode/snmp/smux.h>int smux_close ( reason)
int reason;
The smux_close subroutine closes the transmission control protocol (TCP) connection from the SNMP multiplexing (SMUX) peer. The smux_close subroutine sends the close protocol data unit (PDU) with the error code set to the reason value. The subroutine closes the TCP connection and frees the socket. This subroutine also frees information it was maintaining for the connection.
This subroutine is part of the SNMP Application Programming Interface in the TCP/IP facility.
