  • Data - user data associated with the opened file
  • Offset - position from which the file is read
  • Buffer - buffer that contains read data
  • BufferOffset - start position in the buffer from which the data must be read
  • Count - amount of bytes to be read
  • Read - amount of bytes have been actually read
  • ErrorCode - the error code, see values below
  • Comment - server comment
  • pcComment - server comment
  • szComment - the length of pcComment.

Error codes values:


    This event is fired when the file contents must be read and sent to the client.
The application can return the error code in ErrorCode parameter and textual comment in Comment parameter.
