Hi, i need your help in some issue.
i'm trying to work in curses mode and i have problem with resizing
(minimizing) a window of a terminal.
my signal handler function is :
void sig_winch(int signo)
    struct winsize size;
    ioctl(fileno(stdout), TIOCGWINSZ, (char*)&size);
   resizeterm(size.ws_row, size.ws_col);

There's two issues - it's not safe to put resizeterm in the signal handler.

after getting the signal SIGWINCH( when i'm minimizing the window) i see the
output on the window is ok, and when i try to print with printw() or
addstr() i see the half of the window is deleted. How i can to solve this

resizeterm is only going to repaint the parts of the window that grew - with blanks. Perhaps that's what you are seeing.
