I am writing a program to display a database to the screen(xterm) and want to allow the window resize signal to increase/decrease the amount data that is displayed. I have a signal handler function for catching the SIGWINCH event and calling a function to reallocate the space for the windows (stdscr and curscr) an reallocate the space for the windows.

The resize function looks something like:

//GLOBAL CONSTANTS, initialized elsewhere to the correct values
WINDOW* display;
int maxX;
int maxY;

// resize event function
void resizeHandler() {
   WINDOW*curscrOld = curscr;
   WINDOW*stdscrOld = stdscr;

   endwin();
   delwin(curscrOld);
   delwin(stdscrOld);

   display = initscr();
   getmaxyx(display, maxY, maxX);

   signal(SIGWINCH, resizeHandler);
}    

The problem with the reallocation function seems to be that I put in another call to initscr(). Not every time, but frequently enough to be annoying, the program will have a segmentation fault during the call to initscr() when a resize event occurs. The reason I put in another call to initscr() was getmaxyx() was not updating the size of the window on a resize event. I tried to just use the endwin() and refresh() functions to reinitialize the values returned from getmaxyx(), with no luck.

Inorder to try and get around this error I have been working to remove the additional call to initscr() by deleting and then creating both stdscr and curscr WINDOWS. I managed to find out about the ioctl() function that returns the lines and columns of the term window so that I know what size I want the new windows to be. I have been having limited sucess with this approach. After I create the new windows my first call to refresh() results in yet another segmentation fault. The new code looks something like this:

//GLOBAL CONSTANTS, initialized elsewhere to the correct values
WINDOW* display;
int maxX;
int maxY;

// resize event function
void resizeHandler() {
   struct winsize disp;

   endwin();
   delwin(curscr);
   delwin(stdscr);

   ioctl(STDIN_FILENO, TIOCGWINSZ, &disp)

   LINES = disp.ws_lines;
   COLS = disp.ws_cols;

   newwin(curscr, 0, 0, 0, 0);
   newwin(stdscr, 0, 0, 0, 0);

   werase(curscr);
   wrefresh(curscr);
   wmove(curscr, 0, 0);

   werase(stdscr);
   wrefresh(stdscr);
   wmove(stdscr, 0, 0);

   signal(SIGWINCH, resizeHandler);
}    

I have tried it with and without resetting the curscr variable, which seems to make no difference. Thanks in advance for your help.
