The
newpad()
function creates a new pad of size
lines
,
cols
.
subpad()
is similar to
newpad(
)
excepting that the size of the subpad is bounded by the parent
pad
pad
.
The subpad shares internal data structures with the parent pad
and will be refreshed when the parent pad is refreshed.
The starting column and row
begin_y
,
begin_x
are relative to the parent pad origin.
The
pnoutrefresh()
function performs the internal processing required by curses to determine
what changes need to be made to synchronise the internal screen buffer
and the terminal but does not modify the terminal display.
A rectangular area of the pad starting at column and row
pbeg_y
,
pbeg_x
is copied to the corresponding rectangular area of the screen buffer starting
at column and row
sbeg_y
,
sbeg_x
and extending to
smax_y
,
smax_x
.
The
prefresh()
function causes curses to propagate changes made to the pad specified by
pad
to the terminal display.
A rectangular area of the pad starting at column and row
pbeg_y
,
pbeg_x
is copied to the corresponding rectangular area of the terminal starting
at column and row
sbeg_y
,
sbeg_x
and extending to
smax_y
,
smax_x
.
The
pnoutrefresh()
and
doupdate(
)
functions can be used together to speed up terminal redraws by
deferring the actual terminal updates until after a batch of updates
to multiple pads has been done.
NULL
if an error is detected.
The functions that return an int will return one of the following
values:
OK
ERR
)
function is similar to the
derwin(3)
function, and not the
subwin(3)
function.
