проклятие расширения указателя экрана (curses screen-pointer extension)
Описание (Description)
This implementation can be configured to provide a set of
functions which improve the ability to manage multiple screens.
This feature can be added to any of the configurations supported
by ncurses; it adds new entrypoints without changing the meaning
of any of the existing ones.
IMPROVED FUNCTIONS
Most of the functions are new versions of existing functions. A
parameter is added at the front of the parameter list. It is a
SCREEN pointer.
The existing functions all use the current screen, which is a
static variable. The extended functions use the specified
screen, thereby reducing the number of variables which must be
modified to update multiple screens.
NEW FUNCTIONS
Here are the new functions:
ceiling_panel
this returns a pointer to the topmost panel in the given
screen.
ground_panel
this returns a pointer to the lowest panel in the given
screen.
new_prescr
when creating a new screen, the library uses static
variables which have been preset, e.g., by use_env(3X),
filter(3X), etc. With the screen-pointer extension, there
are situations where it must create a current screen before
the unextended library does. The new_prescr function is
used internally to handle these cases. It is also provided
as an entrypoint to allow applications to customize the
library initialization.
