+                 Put the window size information associated with the terminal
+                 in the winsize structure pointed to by ws.  The window size
+                 structure contains the number of rows and columns (and pixels
+                 if appropriate) of the devices attached to the terminal.  It
+                 is set by user software and is the means by which most
+                 full-screen oriented programs determine the screen size.  The
+                 winsize structure is defined in <sys/ioctl.h>.
