.SH NAME
|
|
\fBresizeterm\fR - change the curses terminal size
|
|
..
|
|
.SH SYNOPSIS
|
|
\fB#include <curses.h>\fR
|
|
|
|
\fBint resizeterm(int lines, int columns);\fR
|
|
..
|
|
.SH DESCRIPTION
|
|
This is an extension to the curses library.
|
|
It provides callers with a hook into the \fBncurses\fR data to resize windows,
|
|
primarily for use by programs running in an X Window terminal (e.g., xterm).
|
|
The function \fBresizeterm\fR resizes the standard and current windows
|
|
to the specified dimensions, and adjusts other bookkeeping data used by
|
|
the \fBncurses\fR 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.
|
|
..
|
|
.SH RETURN VALUE
|
|
The function returns the integer \fBERR\fR upon failure and \fBOK\fR 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.
|
|
..
|
|
.SH 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 \fBmalloc\fR or \fBrealloc\fR may have been interrupted,
|
|
since it uses those functions.
|
|
..
|
|
.PP
|
|
If ncurses is configured to supply its own SIGWINCH handler,
|
|
the \fBresizeterm\fR function ungetch's a \fBKEY_RESIZE\fR which
|
|
will be read on the next call to \fBgetch\fR.
|
|
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.
