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.
