AddPort function

The AddPort function adds the name of a port to the list of supported ports. The AddPort function is exported by the port monitor.

Syntax


BOOL AddPort(
  _In_  LPTSTR pName,
  _In_  HWND hWnd,
  _In_  LPTSTR pMonitorName
);

Parameters

pName [in]

A pointer to a zero-terminated string that specifies the name of the server to which the port is connected. If this parameter is NULL, the port is local.

hWnd [in]

A handle to the parent window of the AddPort dialog box.

pMonitorName [in]

A pointer to a zero-terminated string that specifies the monitor associated with the port.

Return value

If the function succeeds, the return value is a nonzero value.

If the function fails, the return value is zero.

Remarks

Note  This is a blocking or synchronous function and might not return immediately. How quickly this function returns depends on run-time factors such as network status, print server configuration, and printer driver implementation—factors that are difficult to predict when writing an application. Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.

The AddPort function browses the network to find existing ports, and displays a dialog box for the user. The AddPort function should validate the port name entered by the user by calling EnumPorts to ensure that no duplicate names exist.

The caller of the AddPort function must have SERVER_ACCESS_ADMINISTER access to the server to which the port is connected.

To add a port without displaying a dialog box, call the XcvData function instead of AddPort. For more information about XcvData, see the Microsoft Windows Driver Development Kit (DDK).
