Confirmed by a hardware test and a quick diassembly of /dev/es.
I'm not aware of anything that opens several ES handles, but
technically, this fixes a small inaccuracy in IOS HLE.
For IOCTL_STM_EVENTHOOK, IOS checks if there is already an event hook
to prevent overriding an existing event hook message with a new one,
without first releasing it.
Removes #defines which have been unused for years and cleans up
naming.
This also changes IPC_REP_ASYNC to simply IPC_REPLY because it turns
out it's actually not specific to async replies, but used for all
command replies.
- Use an enum instead of defines.
- Only use the FS_ prefix for return codes which are actually related
to FS stuff, not for everything.
- Remove duplicated error codes and clean up the names.
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.
