curs_initscr(3X)					      curs_initscr(3X)

NAME
     curs_initscr:  initscr, newterm, endwin, isendwin, set_term, delscreen -
     curses screen initialization and manipulation routines

SYNOPSIS
     #include <curses.h>

     WINDOW *initscr(void);
     int endwin(void);
     int isendwin(void);
     SCREEN *newterm(char *type, FILE *outfd, FILE *infd);
     SCREEN *set_term(SCREEN *new);
     void delscreen(SCREEN* sp);

DESCRIPTION
     initscr is almost always the first routine that should be called (the
     exceptions are slk_init, filter, ripoffline, use_env and, for multiple-
     terminal applications, newterm.)  This determines the terminal type and
     initializes all curses 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.  If the program needs an indication of
     error conditions, newterm() should be used instead of initscr; initscr
     should only be called once per application.

     A program that outputs to more than one terminal should use the newterm
     routine for each terminal instead of initscr.  A program that needs an
     indication of error conditions, so it can continue to run in a line-
     oriented mode if the terminal cannot support a screen-oriented program,
     would also use this routine.  The routine newterm should be called once
     for each terminal.	 It returns a variable of type SCREEN * which should
     be saved as a reference to that terminal.	The arguments are the type of
     the terminal to be used in place of $TERM, a file pointer for output to
     the terminal, and another file pointer for input from the terminal (if
     type is NULL, $TERM will be used).	 The program must also call endwin for
     each terminal being used before exiting from curses.  If newterm is
     called more than once for the same terminal, the first terminal referred
     to must be the last one for which endwin is called.

     A program should always call endwin before exiting or escaping from
     curses mode temporarily.  This routine restores tty modes, moves the
     cursor to the lower left-hand corner of the screen and resets the
     terminal into the proper non-visual mode.	Calling refresh or doupdate
     after a temporary escape causes the program to resume visual mode.

     The isendwin routine returns TRUE if endwin has been called without any
     subsequent calls to wrefresh, and FALSE otherwise.

     The set_term routine is used to switch between different terminals.  The
     screen reference new becomes the new current terminal.  The previous
     terminal is returned by the routine.  This is the only routine which
     manipulates SCREEN pointers; all other routines affect only the current
     terminal.

     The delscreen routine frees storage associated with the SCREEN data
     structure.	 The endwin routine does not do this, so delscreen should be
     called after endwin if a particular SCREEN is no longer needed.

RETURN VALUE
     endwin returns the integer ERR upon failure and OK upon successful
     completion.

     Routines that return pointers always return NULL on error.

NOTES
     The header file <curses.h> automatically includes the header files
     <stdio.h> and <unctrl.h>.

     Note that initscr and newterm may be macros.
