LOGGING_PARAMETERS Structure

Defines the information for FTP activity, such as user name, session ID, IP addresses for the client and server. Developers can select which logging information to use when they implement the IFtpLogProvider interface.

Syntax

struct LOGGING_PARAMETERS 
{ 
   LPWSTR pszSessionId; 
   LPWSTR pszSiteName; 
   LPWSTR pszUserName; 
   LPWSTR pszHostName; 
   LPWSTR pszRemoteIpAddress; 
   unsigned long dwRemoteIpPort; 
   LPWSTR pszLocalIpAddress; 
   unsigned long dwLocalIpPort; 
   unsigned __int64 BytesSent; 
   unsigned __int64 BytesReceived; 
   LPWSTR pszCommand; 
   LPWSTR pszCommandParameters; 
   LPWSTR pszFullPath; 
   unsigned long dwElapsedMilliseconds; 
   unsigned long FtpStatus; 
   unsigned long FtpSubStatus; 
   HRESULT hrStatus; 
   LPWSTR pszInformation; 
};

Example

The following code example illustrates how to use the IFtpLogProvider interface to create a custom logging module for the FTP service.

public: 
   STDMETHOD(Log)(LOGGING_PARAMETERS * pLoggingParameters) 
   { 
      // Note: You would add your own custom logic here. 
      HRESULT hr = S_OK; 
      DWORD dwResult; 
      HANDLE hFile; 
      char szLogEntry[256]=""; 
      const DWORD FILE_WRITE_TO_END_OF_FILE = 0xffffffff; 
 
      OVERLAPPED Overlapped = { 0 }; 
      Overlapped.Offset = FILE_WRITE_TO_END_OF_FILE; 
      Overlapped.OffsetHigh = -1; 
 
      // Retrieve the current date and time for the log entry. 
      SYSTEMTIME CurrentTime; 
      GetSystemTime(&CurrentTime); 
 
      // Open the log file for output. 
      hFile = CreateFile( 
         L"\\\\?\\C:\\logfiles\\myftpsite\\myftplog.log", 
         GENERIC_WRITE, 
         FILE_SHARE_READ, 
         NULL, 
         OPEN_ALWAYS, 
         FILE_ATTRIBUTE_NORMAL | FILE_FLAG_WRITE_THROUGH, 
         NULL); 
 
      // Return an error if a failure occurs. 
      if (hFile == INVALID_HANDLE_VALUE) 
      { 
         hr = HRESULT_FROM_WIN32(GetLastError()); 
         goto EXIT; 
      } 
 
      // Format the log entry. 
      hr = StringCchPrintfA( 
         szLogEntry,256, 
         "%04d-%02d-%02d\t%02d:%02d:%02d\t%S\t%d\r\n", 
         CurrentTime.wYear,CurrentTime.wMonth,CurrentTime.wDay, 
         CurrentTime.wHour,CurrentTime.wMinute,CurrentTime.wSecond, 
         pLoggingParameters->pszCommand, 
         pLoggingParameters->FtpStatus); 
 
      // Test for error. 
      if (FAILED(hr)) 
      { 
         // Return the error if a failure occurs. 
         hr = HRESULT_FROM_WIN32(GetLastError()); 
         goto EXIT; 
      } 
 
      // Write the log entry to the log file. 
      if(!WriteFile(hFile, szLogEntry, 
         strlen(szLogEntry), &dwResult, &Overlapped)) 
      { 
         // Return an error if a failure occurs. 
         hr = HRESULT_FROM_WIN32(GetLastError()); 
         goto EXIT; 
      } 
 
EXIT: 
      // Close the log file if it is open. 
      if(CloseHandle(hFile)==0) 
      { 
         // Return an error if a failure occurs. 
         hr = HRESULT_FROM_WIN32(GetLastError()); 
      } 
      return hr; 
   }
