File Translation Constants (Windows Embedded CE 6.0)
1/5/2010
These constants specify the mode of translation ("b" or "t").
The mode is included in the string specifying the type of access ("r", "w", "a", "r+", "w+", "a+").
#include <stdio.h>
Remarks
The translation modes are as follows:
t
Opens in text (translated) mode.In this mode, carriage-return/linefeed (CR-LF) combinations are translated into single linefeeds (LF) on input, and LF characters are translated into CR-LF combinations on output.
Also, CTRL+Z is interpreted as an end-of-file character on input.
In files opened for reading or reading/writing, fopen checks for CTRL+Z at the end of the file and removes it, if possible. This is done because using the fseek and ftell functions to move within a file ending with CTRL+Z might cause fseek to behave improperly near the end of the file.
Note
The t option is not part of the ANSI standard for fopen. It is a Microsoft extension and should not be used where ANSI portability is needed.
- b
Opens in binary (untranslated) mode. The above translations are suppressed.
