'stty size' retrieves the info from an ioctl(1,TIOCGWINSZ) call and an
ioctl(0,TIOCGWINSZ) call. Even the value of environment variable COLUMNS
is ignored in this case (I have set COLUMNS=72, for testing).
The terminal in this case is a Solaris console, not a X11 based terminal
emulator.
Find attached the output of
truss src/stty 2>&1 | tee truss.out
truss -u a.out src/stty 2>&1 | tee truss-u.out
Btw, I find the output of the latter (call hierarchy within the main executable)
quite interesting; do we have a similar tool on Linux?
