_PORT_DATA_1 structure

Description

The XcvData function uses a PORT_DATA_1 structure when it adds a port or configures an existing port.

Members

sztPortName

Specifies the name of the port. The MAX_PORTNAME_LEN constant is defined in tcpxcv.h.

dwVersion

Specifies the version number of the PORT_DATA_1 structure, which is currently 1.

dwProtocol

Specifies the protocol to use for the port. This value can be either PROTOCOL_RAWTCP_TYPE or PROTOCOL_LPR_TYPE, constants that are defined in tcpxcv.h.

cbSize

Specifies the size, in bytes of this structure. Use sizeof(PORT_DATA_1) for this value.

dwReserved

Reserved, must be set to zero.

sztHostAddress

Specifies the IP Address or host name of the printer. The MAX_NETWORKNAME_LEN constant is defined in tcpxcv.h.

sztSNMPCommunity

Specifies the SNMP community name of the printer. The MAX_SNMP_COMMUNITY_STR_LEN constant is defined in tcpxcv.h.

dwDoubleSpool

If TRUE, indicates that double spooling is enabled. If FALSE, double spooling is disabled.

sztQueue

Specifies the LPR queue name. The MAX_QUEUENAME_LEN constant is defined in tcpxcv.h.

sztIPAddress

Specifies the IP address of the printer. The MAX_IPADDR_STR_LEN constant is defined in tcpxcv.h.

Reserved

Reserved, must be set to zero.

dwPortNumber

Specifies the port number of the device.

dwSNMPEnabled

If TRUE, indicates that the device supports Simple Network Management Protocol (SNMP).

dwSNMPDevIndex

Specifies the SNMP device index.

Remarks

When the XcvData function is called either to add a port or configure an existing port, its pOutputData parameter must be set with the address of a PORT_DATA_1 structure, which will be filled in when the function returns. To add a port, set this function's pszDataName parameter to the string L"AddPort". To configure a port, set this parameter to L"ConfigPort".

See TCPMON Xcv Interface for more information.
