resizeterm(3) resizeterm(3)
NAME
resizeterm - change the curses terminal size
SYNOPSIS
#include <curses.h>
int resizeterm(int lines, int columns);
DESCRIPTION
This is an extension to the curses library. It provides
callers with a hook into the curses data to resize win-
dows, primarily for use by programs running in an X Window
terminal (e.g., xterm). The function resizeterm resizes
the standard and current windows to the specified dimen-
sions, and adjusts other bookkeeping data used by the
curses library that record the window dimensions.
When resizing the windows, the function blank-fills the
areas that are extended. The calling application should
fill in these areas with appropriate data.
The function attempts to resize all windows. However, due
to the calling convention of pads, it is not possible to
resize these without additional interaction with the
application.
RETURN VALUE
The function returns the integer ERR upon failure and OK
on success. It will fail if either of the dimensions less
than or equal to zero, or if an error occurs while
(re)allocating memory for the windows.
NOTES
While this function is intended to be used to support a
signal handler (i.e., for SIGWINCH), care should be taken
to avoid invoking it in a context where malloc or realloc
may have been interrupted, since it uses those functions.
If curses is configured to supply its own SIGWINCH han-
dler, the resizeterm function ungetch's a KEY_RESIZE which
will be read on the next call to getch. This is used to
alert an application that the screen size has changed, and
that it should repaint special features such as pads that
cannot be done automatically.
