about industry standards and associated tags.
The scroll routine scrolls the window up one line. This
involves moving the lines in the window data structure. As
an optimization, if the scrolling region of the window is
the entire screen, the physical screen is scrolled at the
The scrl and wscrl routines, for positive n, scroll the
current or specified window up n lines (line i+n becomes
line i); otherwise, these routines scroll the window down
n lines. This operation involves moving the lines in the
window character-image structure. The routines do not
change the current cursor position.
For the scroll, scrl, and wscrl functions to work, the
scrollok option must be enabled.
The header file <curses.h> automatically includes the
header file <stdio.h>.
Note that scrl may be a macro.
All routines return the integer ERR upon failure and OK
upon successful completion.
