SIGWINCH problem

[maxim maxim]

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);
    flushinp();
}

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 problem.

Thank you for your time
