Remarks

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 (0x0D, 0x0A) is sent to the file. When you read, the byte pair (0x0D, 0x0A) is translated to a single 0x0A byte.

The CFile functions Duplicate, LockRange, and UnlockRange are not supported for CStdioFile.

If you call these functions on a CStdioFile, you will get a CNotSupportedException.

For more information on using CStdioFile, see the articles Files in MFC and File Handling in the Run-Time Library Reference.
