SYNOPSIS
       cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib 
       -R /usr/xpg4/lib -lcurses [ library... ]

       void use_env(bool boolval);

PARAMETERS
       boolval	       Is a Boolean expression.

DESCRIPTION
       The  use_env()  function  specifies  the  technique by which the implementation determines the size of the screen. If boolval is FALSE, the
       implementation uses the values of lines and columns specified in the terminfo database. If boolval is TRUE,  the  implementation  uses  the
       LINES and COLUMNS environmental variables. The initial value is TRUE.

       Any call to use_env() must precede calls to initscr(3XCURSES), newterm(3XCURSES), or setupterm(3XCURSES).

RETURN VALUES
       The use_env() function does not return a value.

ERRORS
       No errors are defined.
