File Translation Constants
Visual Studio .NET 2003
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+").
The translation modes are as follows:
- 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 may cause fseek to behave improperly near the end of the file.
Note The t option is not part of the ANSI standard for fopen and freopen. It is a Microsoft extension and should not be used where ANSI portability is desired.
- Opens in binary (untranslated) mode. The above translations are suppressed.
