IOCTL_SERVICE_DEREGISTER_SOCKADDR (Compact 2013)

  • [アーティクル]

3/26/2014

This I/O control message is passed as an input parameter along with the sockaddr structure when Servicesd.exe calls the xxx_IOControl (Servicesd.exe) function to stop a running service. Send this message with DeviceIoControl.

Syntax

BOOL DeviceIoControl(
    HANDLE hDevice,          // handle to the device
    DWORD dwIoControlCode,   // use IOCTL_SERVICE_DEREGISTER_SOCKADDR
    LPVOID lpInBuffer,       // pointer to input buffer
    DWORD nInBufferSize,     // input buffer size
    LPVOID lpOutBuffer,      // pointer to output buffer
    DWORD nOutBufferSize,    // output buffer size
    LPDWORD lpBytesReturned, // number of bytes returned
    OVERLAPPED lpOverlapped  // pointer to OVERLAPPED structure
);

Parameters

  • hDevice
    [in] Handle to the device.
  • dwIoControlCode
    [in] The control code for the operation. Use IOCTL_SERVICE_DEREGISTER_SOCKADDR for this operation.
  • lpInBuffer
    [in] Pointer to a sockaddr structure specifying the protocol, port, and optionally the address that should be used for listening for a particular service.

Return Values

Returns TRUE if successful; otherwise, returns FALSE. To obtain extended error information, call the SetLastError function.

Remarks

If the socket is being closed as a result of a call to the ServiceClosePort function, the particular sockaddr that is being closed will be included as the input parameter. Otherwise, NULL will be passed in to indicate that all a service's listen sockets in the super service thread are being terminated.
