ENHANCED CURSES

NAME

filter — disable use of certain terminal capabilities

SYNOPSIS

#include <curses.h>

void filter(void);

DESCRIPTION

The filter() function changes the algorithm for initialising terminal capabilities that assume that the terminal has more than one line.  A subsequent call to initscr() or newterm() performs the following 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. 

ERRORS

No errors are defined. 

SEE ALSO

Defined Capabilities in terminfo(4), initscr(), <curses.h>.
