Sets binary or text translation mode of a file.

#include <fcntl.h>
#include <io.h>

int setmode (int handle, int mode);

Parameters

handle

Descriptor referring to an open file.

mode

New translation mode.

Remarks

mode must be one of these manifest constants:

setmode is typically used to modify the default translation mode of stdin, stdout, and stderr, but can be used on any file.

Note:   

If multiple threads or processes are collecting data from the same file or stream, use binary mode. Otherwise, the thread or process receives scrambled data.

Do not try to change a stream's mode while the stream buffer is active. Call fflush first.

Return Values

The previous translation mode.

Success.

-1 on error, and the function sets errno to one of these values:

EBADF	Invalid file descriptor.
EINVAL	Invalid mode argument (neither O_TEXT nor O_BINARY).

Failure.
