Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

The function <STRONG>set_menu_spacing</STRONG> sets the spacing information for the
|
|
menu. Its parameters provide the description and the size (in rows and
|
|
columns).
|
|
|
|
<EM>spc</EM><STRONG>_</STRONG><EM>description</EM>
|
|
controls the number of spaces between an item name and an item
|
|
description. It must not be larger than <STRONG>TABSIZE</STRONG>. The menu
|
|
system puts in the middle of this spacing area the pad
|
|
character. The remaining parts are filled with spaces.
|
|
|
|
<EM>spc</EM><STRONG>_</STRONG><EM>rows</EM>
|
|
controls the number of rows that are used for an item. It must
|
|
not be larger than 3. The menu system inserts the blank lines
|
|
between item rows, these lines will contain the pad character in
|
|
the appropriate positions.
|
|
|
|
<EM>spc</EM><STRONG>_</STRONG><EM>columns</EM>
|
|
controls the number of blanks between columns of items. It must
|
|
not be larger than <STRONG>TABSIZE</STRONG>. A value of 0 for all the spacing
|
|
values resets them to the default, which is 1 for all of them.
|
|
|
|
The function <STRONG>menu_spacing</STRONG> returns the spacing information for the menu.
|
|
If a pointer is <EM>NULL</EM>, the corresponding information is simply not
|
|
returned.
|
|
|
|
|
|
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
|
|
Both routines return <STRONG>E_OK</STRONG> on success. <STRONG>set_menu_spacing</STRONG> may return
|
|
<STRONG>E_POSTED</STRONG> if the menu is posted, or <STRONG>E_BAD_ARGUMENT</STRONG> if one of the spacing
|
|
values is out of range.

These routines are specific to <EM>ncurses</EM>. They were not supported on
|
|
Version 7, BSD or System V implementations. It is recommended that any
|
|
code depending on them be conditioned using NCURSES_VERSION.
