Description |

The use_env() routine takes the values for lines and
columns from the terminfo database (if bool is FALSE), or from environmental variables (if bool is TRUE). If no environmental variables have been set, the window size is used. This routine must be set before
initscr(), newterm(), or setupterm() is called. The default action is TRUE.
