FS subfiles are created with File::OpenSubFile, they have a start offset that must be added to all read/write operations.
The implementation in this commit is done using a new FileBackend that wraps the FS::File along with the start offset.
boost::static_pointer_cast for boost::intrusive_ptr (what SharedPtr is),
takes its parameter by const reference. Given that, it means that this
std::move doesn't actually do anything other than obscure what the
function's actual behavior is, so we can remove this. To clarify, this
would only do something if the parameter was either taking its argument
by value, by non-const ref, or by rvalue-reference.
Keeps the toolchain used for CI up to date. Xcode 10 also brings in
better (but not complete) C++17 support on macOS. Notably it allows the
use of the <any>, <optional>, and <variant> headers that were introduced
in C++17, among other things. Now we can use the standard-provided
facilities instead of needing to rely on boost for these.
Github Linguist will read this file when calculating language stats for
the repository. We can use this to exclude any vendored dependencies in
externals and dist. Also makes all h files be considered cpp
Changes the interface as well to remove any unique methods that
frontends needed to call such as StartJoystickEventHandler by
conditionally starting the polling thread only if the frontend hasn't
started it already. Additionally, moves all global state into a single
SDLState class in order to guarantee that the destructors are called in
the proper order
This can just be a regular function, getting rid of the need to also
explicitly undef the define at the end of the file. Given FuncReturn()
was already converted into a function, it's #undef can also be removed.
Instead of using an unsigned int as a parameter and expecting a user to
always pass in the correct values, we can just convert the enum into an
enum class and use that type as the parameter type instead, which makes
the interface more type safe.
We also get rid of the bookkeeping "NUM_" element in the enum by just
using an unordered map. This function is generally low-frequency in
terms of calls (and I'd hope so, considering otherwise would mean we're
slamming the disk with IO all the time) so I'd consider this acceptable
in this case.
