ИМЯ

       TIOCGWINSZ, TIOCSWINSZ - get and set window size

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <asm/termbits.h>  /* Definition of TIOC*WINSZ constants */
       #include <sys/ioctl.h>

       int ioctl(int fd, TIOCGWINSZ, struct winsize *argp);
       int ioctl(int fd, TIOCSWINSZ, const struct winsize *argp);

       #include <asm/termios.h>

       struct winsize {
           unsigned short ws_row;
           unsigned short ws_col;
           unsigned short ws_xpixel;  /* unused */
           unsigned short ws_ypixel;  /* unused */
       };

ОПИСАНИЕ

       Window sizes are kept in the kernel, but not used by the kernel
       (except in the case of virtual consoles, where the kernel will
       update the window size when the size of the virtual console
       changes, for example, by loading a new font).

       TIOCGWINSZ
              Get window size.

       TIOCSWINSZ
              Set window size.

       When the window size changes, a SIGWINCH signal is sent to the
       foreground process group.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, 0 is returned.  On error, -1 is returned, and errno
       is set to indicate the error.
