Name
       typeahead - check for typeahead

Syntax
       int typeahead(fd)
       int fd;

Description
       If is enabled, the program looks for typeahead input periodically while updating the screen.  If input is found, the current update will be
       postponed until or is called again.  This allows faster response to commands typed in advance.

       Normally, the input FILE pointer passed to the routine, will be used to do this typeahead checking.  If the routine was called,	the  input
       FILE pointer is passed to

       The routine specifies that the file descriptor is to be used to check for typeahead.  If is -1, then typeahead is disabled.

Return Values
       No return values are defined for this function.

NAME

       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

       None.
