Size is internally stored as a size_t, so having an int parameter
would cause implicit sign-conversion from a signed value to an
unsigned value to occur.
This removes Open() and Close() functions from devices whenever they
did nothing more than the base class (setting m_Active, returning a
default reply).
Also, since IOS close commands practically always return FS_SUCCESS,
writing the return code is moved to HandleCommand() in WII_IPC_HLE,
which has two benefits: it's not duplicated all over the place
(so people will not forget it) and it gets rid of having to check
the force parameter, since HandleCommand() is always called for
real IOS commands, so command_address is guaranteed to be valid.
It looks like at some point Dolphin device IDs coincided with IOS file
descriptors, but this is not the case anymore, so keeping those
WriteReturnCode(GetDeviceID()) in every single IOS HLE device,
as if the device ID was used as IOS fd, is both unnecessary
and confusing.
Jan 04 22:55:01 <leoetlino> fwiw, it looks like there are new warnings in the RegCache code
Jan 04 22:55:04 <leoetlino> Source/Core/Core/PowerPC/Jit64/FPURegCache.cpp:13:33: warning: declaration shadows a variable in the global namespace [-Wshadow]
Jan 04 22:56:19 <@Lioncash> yeah, the jit global should have a g_ prefix.
This fixes shadowing warnings and adds the g_ prefix to a global.
Other settings options are nouns rather than verbs so this change makes the configuration option consistent with others. Also makes the menu option label the same as the windows title.
We don't really have to keep track of device opens/closes manually,
since we can already check that by calling IsOpened() on the device.
This also replaces some loops with for range loops.
Certain parts of the standard library try to determine whether or not a
transfer operation should either be a copy or a move. The prevalent notion
of move constructors/assignment operators is that they should not throw,
they simply move an already existing resource somewhere else.
This is typically done with 'std::move_if_noexcept'. Like the name says,
if a type's move constructor is noexcept, then the functions retrieves an
r-value reference (for move semantics), or an l-value (for copy semantics)
if it is not noexcept.
As IOFile deletes the copy constructor and copy assignment operators,
using IOFile with certain parts of the standard library can fail in
unexcepted ways (especially when used with various container
implementations). This prevents that.
'operator void*' is basically a pre-C++11-ism that was used, as C++03
only had the notion of implicit type-conversion operators, but not explicit type
conversion operators (allowing implicit conversion of a file handle to
bool can go downhill pretty quickly).
