SYNOPSIS
#include <curses.h>
void use_env(bool boolvalue);
DESCRIPTION

the implementation uses the values of lines and columns specified
in the terminfo database. If boolvalue is TRUE, the implementation uses
the

and
COLUMNS
environment variables. The initial value is TRUE.
Any call to
use_env()
must precede calls to
initscr(),
newterm()
or
setupterm().
