SetPort info  Overview  Group

The SetPort function sets the status associated with a printer port.

BOOL SetPort(

    LPTSTR pName,

// pointer to a printer server name

    LPTSTR pPortName,

// pointer to a printer port name

    DWORD dwLevel, 

// version of PORT_INFO_* structure

    LPBYTE pPortInfo 

// pointer to a PORT_INFO_* structure



Pointer to a zero-terminated string that specifies the name of the printer server to which the port is connected. Set this parameter to NULL if the port is on the local machine.
Pointer to a zero-terminated string that specifies the name of the printer port.
Specifies the type of PORT_INFO_* structure pointed to by the pPortInfo parameter.

This value must be 3, which corresponds to a PORT_INFO_3 data structure.

Pointer to a PORT_INFO_3 structure that contains the port status information to set.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.


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

When you set a printer port status value with the severity value PORT_STATUS_TYPE_ERROR, the print spooler stops sending jobs to the port. The print spooler resumes sending jobs to the port when the port status is cleared by another call to SetPort.
