Function: set-window-hscroll
set-window-hscroll is a function defined in window.c.
Signature
(set-window-hscroll WINDOW NCOL)
Documentation
Set number of columns WINDOW is scrolled from left margin to NCOL.
WINDOW must be a live window and defaults to the selected one. Clip the number to a reasonable value if out of range. Return the new number. NCOL should be zero or positive.
Note that if auto-hscroll-mode is non-nil, you cannot scroll the
window so that the location of point moves off-window.
Probably introduced at or before Emacs version 21.1.
