TCPMON Xcv commands
This section describes the commands that can be specified in a call to the XcvData or XcvDataPort function, when it is communicating with the standard TCP/IP port monitor (TCPMON). Each command is specified by the pszDataName string in the call to these functions. Certain commands require an input buffer, or an output buffer, or both. The pInputData and pOutputData parameters of these functions hold the addresses of these buffers.
The table that appears in the description of each of the following commands lists the XcvData and XcvDataPort parameters that are used with the commands. Note that the hXcv parameter (common to both functions) is not listed, nor is the XcvData function's pdwStatus parameter.
AddPort command
The AddPort command adds a standard TCP/IP port, which can be either an LPR port or a RAW TCP/IP port.
| XcvData parameter | Value |
|---|---|
| pszDataName | L"AddPort" |
| pInputData | Address of a PORT_DATA_1 structure |
| cbInputData | sizeof(PORT_DATA_1) |
| pOutputData | NULL |
| cbOutputData | 0 |
| pcbOutputNeeded | Address of a DWORD |
XcvData returns NO_ERROR if it can add the port. In addition to the normal error codes, XcvData returns ERROR_ACCESS_DENIED if the user has insufficient privileges to create a port on the server. This command requires SERVER_ACCESS_ADMINISTER privilege. If the pInputData parameter is NULL, the function returns ERROR_INVALID_DATA. If pInputData-->dwVersion is not equal to 1, the function returns ERROR_INVALID_LEVEL.
ConfigPort command
The ConfigPort command configures an existing standard TCP/IP port monitor port.
| XcvData parameter | Value |
|---|---|
| pszDataName | L"ConfigPort" |
| pInputData | Address of a PORT_DATA_1 structure |
| cbInputData | sizeof(PORT_DATA_1) |
| pOutputData | NULL |
| cbOutputData | 0 |
| pcbOutputNeeded | Address of a DWORD |
XcvData returns NO_ERROR if it can configure the port. In addition to the normal error codes, XcvData returns ERROR_ACCESS_DENIED if the caller has insufficient privileges to perform the request. This command requires SERVER_ACCESS_ADMINISTER privilege. If the pInputData parameter is NULL, or the value in cbInputData is smaller than required, the function returns ERROR_INVALID_DATA. If pInputData-->dwVersion is not equal to 1, the function returns ERROR_INVALID_LEVEL.
DeletePort command
The DeletePort command deletes a port from the standard TCP/IP port monitor.
| XcvData parameter | Value |
|---|---|
| pszDataName | L"DeletePort" |
| pInputData | Address of DELETE_PORT_DATA_1 structure |
| cbInputData | sizeof(DELETE_PORT_DATA_1) |
| pOutputData | NULL |
| cbOutputData | 0 |
| pcbOutputNeeded | Address of a DWORD |
XcvData returns NO_ERROR if the port is successfully deleted. In addition to the normal error codes, XcvData returns ERROR_ACCESS_DENIED if the caller has insufficient privileges on the server. This command requires SERVER_ACCESS_ADMINISTER privilege. If the pInputData parameter is NULL, or if the cbInputData parameter is smaller than required, the function returns ERROR_INVALID_DATA. If pInputData-->dwVersion is not equal to 1, the function returns ERROR_INVALID_LEVEL.
GetConfigInfo command
The GetConfigInfo command obtains the configuration information of a particular port. In this case, the Xcv data handle must point to a particular standard TCP/IP port monitor port so that the port can be identified.
| XcvData parameter | Value |
|---|---|
| pszDataName | L"GetConfigInfo" |
| pInputData | Address of a CONFIG_INFO_DATA_1 structure |
| cbInputData | sizeof(CONFIG_INFO_DATA_1) |
| pOutputData | Address of a PORT_DATA_1 structure |
| cbOutputData | sizeof(PORT_DATA_1) |
| pcbOutputNeeded | Address of a DWORD containing the number of bytes needed for the buffer pointed to by pOutputData |
XcvData returns NO_ERROR if it can obtain the configuration information for the port. If pInputData is NULL, or if cbInputData is smaller than required, the function returns ERROR_INVALID_DATA. If pInputData-->dwVersion is not equal to 1, the function returns ERROR_INVALID_LEVEL. If cbOutputData is smaller than required, the function returns ERROR_INVALID_PARAMETER when pcbOutputNeeded is NULL, and ERROR_INSUFFICIENT_BUFFER when pcbOutputNeeded is non-NULL.
HostAddress command
The HostAddress command gets the printer's host name.
| XcvData parameter | Value |
|---|---|
| pszDataName | L"HostAddress" |
| pInputData | NULL |
| cbInputData | 0 |
| pOutputData | Address of a buffer that receives a string containing the printer's host name |
| cbOutputData | Size of the buffer pointed to by pOutputData |
| pcbOutputNeeded | Address of a DWORD containing the number of bytes needed for the buffer pointed to by pOutputData |
XcvData returns NO_ERROR if it can obtain the name of the printer's host. If cbOutputData is smaller than required, the function returns ERROR_INVALID_PARAMETER when pcbOutputNeeded is NULL, and ERROR_INSUFFICIENT_BUFFER when pcbOutputNeeded is non-NULL. If pOutputData is NULL, the function returns ERROR_INVALID_PARAMETER.
IPAddress command
The IPAddress command gets the printer's IP address.
| XcvData parameter | Value |
|---|---|
| pszDataName | L"IPAddress" |
| pInputData | NULL |
| cbInputData | 0 |
| pOutputData | Address of a buffer that receives a string containing the printer's IP address |
| cbOutputData | Size of the buffer pointed to by pOutputData |
| pcbOutputNeeded | Address of a DWORD containing the number of bytes needed for the buffer pointed to by pOutputData |
XcvData returns NO_ERROR if it can obtain the printer's IP address. If cbOutputData is smaller than required, the function returns ERROR_INVALID_PARAMETER when pcbOutputNeeded is NULL, and ERROR_INSUFFICIENT_BUFFER when pcbOutputNeeded is non-NULL. If pOutputData is NULL, the function returns ERROR_INVALID_PARAMETER.
MonitorUI command
The MonitorUI command gets the name of the port monitor UI DLL that provides an interface to TCPMON.
| XcvData parameter | Value |
|---|---|
| pszDataName | L"MonitorUI" |
| pInputData | NULL |
| cbInputData | 0 |

| cbOutputData | Number of bytes in the string containing the name of the port monitor user interface DLL |
| pcbOutputNeeded | Address of a DWORD containing the number of bytes needed for the buffer pointed to by pOutputData |
XcvData returns NO_ERROR if it is able to obtain the name of the user interface DLL. In addition to the normal error codes, XcvData returns ERROR_ACCESS_DENIED if the caller has insufficient privileges on the server. This command requires SERVER_ACCESS_ADMINISTER privilege. If cbOutputData is smaller than required, the function returns ERROR_INVALID_PARAMETER when pcbOutputNeeded is NULL, and ERROR_INSUFFICIENT_BUFFER when pcbOutputNeeded is non-NULL. If pOutputData is NULL, the function returns ERROR_INVALID_PARAMETER.
