INITSCR(3XCURSES) X/Open Curses Library Functions INITSCR(3XCURSES)

NAME


initscr, newterm - screen initialization functions

SYNOPSIS


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

c89 [ flag... ] file... -lcurses [ library... ]

#include <curses.h>

WINDOW *initscr(void);


SCREEN *newterm(char *type, FILE *outfp, FILE *infp);


PARAMETERS


type
Is a string defining the terminal type to be used in place of
TERM.


outfp
Is a pointer to a file to be used for output to the terminal.


infp
Is the pointer to a file to be used for input to the terminal.


DESCRIPTION


The initscr() function initializes X/Open Curses data structures,
determines the terminal type, and ensures the first call to
refresh(3XCURSES) clears the screen.


The newterm() function opens a new terminal with each call. It should be
used instead of initscr() when the program interacts with more than one
terminal. It returns a variable of type SCREEN, which should be used for
later reference to that terminal. Before program termination, endwin()
should be called for each terminal.


The only functions that you can call before calling initscr() or
newterm() are filter(3XCURSES), ripoffline(3XCURSES), slk_init(3XCURSES),
and use_env(3XCURSES).

RETURN VALUES


On success, the initscr() function returns a pointer to stdscr;
otherwise, initscr() does not return.


On success, the newterm() function returns a pointer to the specified
terminal; otherwise, a null pointer is returned.

ERRORS


None.
