Do you mean before ls program output it's result,it would get some attributes
from file descriptor 1 such as the screen width? If it can't get it,it would
just output the simple format as one filename per line?

I will answer your question with a question, if I may. How many
columns are available in an as-yet-empty output file? There's no
obvious answer. Therefore there is no obvious width at which the
output should wrap. Also, data sent to a file is frequently read by
another program for further processing. If that is happening, one
filename per line is probably a convenient choice.
