NAME

       TIOCGWINSZ, TIOCSWINSZ - get and set window size

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #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 */
       };

DESCRIPTION

       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.

RETURN VALUE

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