echo(3XCURSES)						  X/Open Curses Library Functions					    echo(3XCURSES)

echo, noecho - enable/disable terminal echo SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib -R /usr/xpg4/lib -lcurses [ library... ] c89 [ flag... ] file... -lcurses [ library... ] #include <curses.h> int echo(void); int noecho(void); DESCRIPTION
The echo() function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially, curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control soft- ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined. RETURN VALUES
Upon successful completion, these functions return OK. Otherwise, they return ERR. ERRORS
No errors are defined. ATTRIBUTES

typeahead - check for type-ahead characters SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib -R /usr/xpg4/lib -lcurses [ library... ] c89 [ flag... ] file... -lcurses [ library... ] #include <curses.h> int typeahead(int fd); PARAMETERS
fd Is the file descriptor that is used to check for type-ahead characters. DESCRIPTION
The typeahead() function specifies the file descriptor (fd) to use to check for type-ahead characters (characters typed by the user but not yet processed by X/Open Curses). X/Open Curses checks for type-ahead characters periodically while updating the screen. If characters are found, the current update is postponed until the next refresh(3XCURSES) or doupdate(3XCURSES). This speeds up response to commands that have been typed ahead. Nor- mally, the input file pointer passed to newterm(3XCURSES), or stdin in the case of initscr(3XCURSES), is used for type-ahead checking. If fd is -1, no type-ahead checking is done. RETURN VALUES
On success, the typeahead() function returns OK. Otherwise, it returns ERR. ERRORS
