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

filter - disable use of certain terminal capabilities

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>
void filter(void);

The filter() function changes how X/Open Curses initializes terminal capabilities that assume the terminal has more than one line. After a call to filter(), the initscr(3XCURSES) or newterm(3XCURSES) functions also:

Disable use of clear, cud, cud1, cup, cuu1, and vpa.
Set home string to the value of cr.
Set lines to 1.

The filter() function does not return a value.
