  Description
 
  A CStdioFile object represents a C run-time stream file as opened by the
  fopen function. Stream files are buffered and can be opened in either
  text mode (the default) or binary mode.
 
  Text mode provides special processing for carriage return-linefeed
  pairs. When you write a newline character (0x0A) to a text-mode
  CStdioFile object, the byte pair (0x0A, 0x0D) is sent to the file. When
  you read, the byte pair (0x0A, 0x0D) is translated to a single 0x0A
  byte.
