NAME
nl, nonl — enable/disable newline translation
SYNOPSIS
#include <curses.h>
int nl(void);
int nonl(void);
DESCRIPTION
The
nl()
function enables a mode in which carriage return is translated to newline on
input. The
nonl()
function disables the above translation.
Initially, the above translation is enabled.
RETURN VALUE
Upon successful completion, these functions return OK. Otherwise, they return
ERR.
ERRORS
No errors are defined.
APPLICATION USAGE
The default translation adapts the terminal to environments in which newline
is the line termination character. However, by disabling the translation with
nonl(),
the application can sense the pressing of the carriage return key.
CHANGE HISTORY

The argument list for the
nl()
and

functions is explicitly declared as void.
