pub fn initscr() -> Result<WINDOW, NCurseswError>Expand description
Initialize the NCurses data structures and return the standard screen.
initscr() is normally the first NCurses routine to call when initializing
a program. A few special routines sometimes need to be called before it; these
are slk_init(), filter(), ripoffline(), use_env(). For multiple-terminal
applications, newterm() may be called before initscr().
The initscr() code determines the terminal type and initializes all NCurses data
structures. initscr() also causes the first call to refresh() to clear the
screen. If errors occur, initscr() writes an appropriate error message to
standard error and exits; otherwise, a pointer is returned to stdscr().
