- Name: initscr
-
- Synopsis:
- WINDOW *initscr(void);
- WINDOW *Xinitscr(int argc, char *argv[]);
- int endwin(void);
- bool isendwin(void);
- SCREEN *newterm(const char *type, FILE *outfd, FILE *infd);
- SCREEN *set_term(SCREEN *new);
- void delscreen(SCREEN *sp);
-
- int resize_term(int nlines, int ncols);
- bool is_termresized(void);
- const char *curses_version(void);
-
- Description:
- initscr() should be the first curses routine called. It will
- initialize all curses data structures, and arrange that the
- first call to refresh() will clear the screen. In case of
- error, initscr() will write a message to standard error and end
- the program.
-
- endwin() should be called before exiting or escaping from curses
- mode temporarily. It will restore tty modes, move the cursor to
- the lower left corner of the screen and reset the terminal into
- the proper non-visual mode. To resume curses after a temporary
- escape, call refresh() or doupdate().
-
- isendwin() returns TRUE if endwin() has been called without a
- subsequent refresh, unless SP is NULL.
-
- In some implementations of curses, newterm() allows the use of
- multiple terminals. Here, it's just an alternative interface for
- initscr(). It always returns SP, or NULL.
-
- delscreen() frees the memory allocated by newterm() or
- initscr(), since it's not freed by endwin(). This function is
- usually not needed. In PDCurses, the parameter must be the
- value of SP, and delscreen() sets SP to NULL.
-
- set_term() does nothing meaningful in PDCurses, but is included
- for compatibility with other curses implementations.
-
- resize_term() is effectively two functions: When called with
- nonzero values for nlines and ncols, it attempts to resize the
- screen to the given size. When called with (0, 0), it merely
- adjusts the internal structures to match the current size after
- the screen is resized by the user. On the currently supported
- platforms, this functionality is mutually exclusive: X11 allows
- user resizing, while DOS, OS/2 and Win32 allow programmatic
- resizing. If you want to support user resizing, you should check
- for getch() returning KEY_RESIZE, and/or call is_termresized()
- at appropriate times; if either condition occurs, call
- resize_term(0, 0). Then, with either user or programmatic
- resizing, you'll have to resize any windows you've created, as
- appropriate; resize_term() only handles stdscr and curscr.
-
- is_termresized() returns TRUE if the curses screen has been
- resized by the user, and a call to resize_term() is needed.
- Checking for KEY_RESIZE is generally preferable, unless you're
- not handling the keyboard.
-
- curses_version() returns a string describing the version of
- PDCurses.
-
- Return Value:
- All functions return NULL on error, except endwin(), which
- returns ERR on error.
