- EditBox: Display the initial contents of the text buffer.
This allows modifying already existing text in the passed buffer.
- Menu:
* Make both MenuHeader and MenuFooter optional (but the latter is
more "optional" than the former...).
* Allow passing a user-provided "Context" structure to the key-press
filter callback, and pass also the index of the menu item that has
been selected.
- Minor formatting fixes.
CORE-9023
- During loading and initialization of the list of operating systems
available in freeldr.ini, convert any legacy operating system entry
encountered -- they are like those in NTLDR's boot.ini file, i.e.:
ArcOsLoadPartition="LoadIdentifier" /List /of /Options
into a new operating system INI entry, like those used by default in
FreeLoader. This allows us to avoid treating this corner-case later in
different parts of the code. Also, the "BootType" value is now
determined there, only once.
- Convert the OS loaders entry-points to ARC-compatible ones, following
the "Advanced RISC Computing Specification, Version 1.2" specification
https://www.netbsd.org/docs/Hardware/Machines/ARC/riscspec.pdf
- Introduce helpers for retrieving options values from the argument vector
in a simple way.
- Simplify LoadOperatingSystem(), since now the "BootType" value has
been determined once while loading the list of OSes (see above) and
is well-defined there. Use the BuildArgvForOsLoader() helper to build
the ARC-compatible argument vector from the corresponding INI settings
for the selected operating system entry, and use it when calling the
corresponding OS loader.
- In the OS loaders, since we can now directly read the settings from
the argument vector (instead of using INI settings), we can avoid
using a bunch of fixed-size string buffers, and avoid potentially
failing IniOpenSection() calls as well.
- Simplify code in the Linux loader (and the RemoveQuotes() function).
- Add UiShowMessageBoxesInArgv() that acts on the "MessageBox=" settings
passed through the argument vector (equivalent to
UiShowMessageBoxesInSection() ).
- Use string-safe functions where needed (copy/concatenation/printf on
fixed-size buffers).
