SYNOPSIS

#include <curses.h>

void filter(void);

DESCRIPTION

terminal has more than one line. A subsequent call to

initscr() or newterm() performs the follow-

ing additional actions:

• Disable use of

clear, cud,

cud1, cup, cuu1 and vpa.

• Set the value of the

home

string to the value of the cr string

• Set

lines equal to 1.

Any call to filter() must precede the call to

initscr() or newterm() .

RETURN VALUE

The

filter() function does not return a value.
