51 These functions create and display pads on the current screen.
55 function creates a new pad of size
62 excepting that the size of the subpad is bounded by the parent
65 The subpad shares internal data structures with the parent pad
66 and will be refreshed when the parent pad is refreshed.
67 The starting column and row
70 are relative to the parent pad origin.
74 function performs the internal processing required by curses to determine
75 what changes need to be made to synchronise the internal screen buffer
76 and the terminal but does not modify the terminal display.
77 A rectangular area of the pad starting at column and row
80 is copied to the corresponding rectangular area of the screen buffer starting
90 function causes curses to propagate changes made to the pad specified by
92 to the terminal display.
93 A rectangular area of the pad starting at column and row
96 is copied to the corresponding rectangular area of the terminal starting
108 functions can be used together to speed up terminal redraws by
109 deferring the actual terminal updates until after a batch of updates
110 to multiple pads has been done.
112 Functions returning pointers will return
114 if an error is detected.
115 The functions that return an int will return one of the following
118 .Bl -tag -width ERR -compact
120 The function completed successfully.
122 An error occurred in the function.
125 .Xr curses_refresh 3 ,
130 function is similar to the
132 function, and not the
138 Curses library complies with the X/Open Curses specification, part of the
139 Single Unix Specification.
