Question

binary
mode I/O functions

Answer 1

Answer:

File I/O operations take place in one of two translation modes, text or binary, depending on the mode in which the file is opened. Data files are usually processed in text mode. To control the file translation mode, one can:

Retain the current default setting and specify the alternative mode only when you open selected files.

Use the function _set_fmode to change the default mode for newly opened files. Use _get_fmode to find the current default mode. The initial default setting is text mode (_O_TEXT).

Change the default translation mode directly by setting the global variable _fmode in your program. The function _set_fmode sets the value of this variable, but it can also be set directly.
