This means the allocator's caller doesn't need to use SDL_OutOfMemory directly
if the allocation fails.
This applies to the usual allocators: SDL_malloc, SDL_calloc, SDL_realloc
(all of these regardless of if the app supplied a custom allocator or we're
using system malloc() or an internal copy of dlmalloc under the hood),
SDL_aligned_alloc, SDL_small_alloc, SDL_strdup, SDL_asprintf, SDL_wcsdup...
probably others. If it returns something you can pass to SDL_free, it should
work.
The caller might still need to use SDL_OutOfMemory if something that wasn't
SDL allocated the memory: operator new in C++ code, Objective-C's alloc
message, win32 GlobalAlloc, etc.
Fixes#8642.
ALSA expects handles to be of type ALSA_Device, and passing the handle for the default device as a plain string causes a crash as it attempts to deference the string contents itself as a pointer to a string.
Create immutable static ALSA_Device structs for the default devices and pass those as the handles. They are not placed in the hotplug list, and the audio layer doesn't attempt to free ALSA handles, so there is no need to worry about them being erroneously freed.
We don't match dev->name by string, since we might use the same string for both capture and output devices. Instead use the device pointer itself as the handle.
@icculus, are we guaranteed the device pointer is valid in ALSA_OpenDevice()?
Fully committing to it...!
This left SDL_wave.* alone for now, since there's a ton of comments in there
and this code hasn't changed much from SDL2 so far. But as SDL2 ages out a
little more, I'll likely switch this over, too.
First stage happens before we destroy objects, and is generally used to
shut down hotplug. The second stage is the usual deinit, which cleans up
the lowlevel API, unloads shared libraries, etc.
This is an attempt to centralize all the error handling, instead of
implicitly counting on WaitDevice implementations to disconnect the device
to report an error.
Now we sleep the thread in WaitDevice until ALSA reawakens it because it
needs more data, and we feed it exactly as much as it can take at that
point.
Like the recent PulseAudio changes, this is both more efficient, reliable,
and consistent.
Every single case of this didn't want the device locked, so just looking
it up without having to immediately unlock it afterwards is better here.
Often these devices are passed on to other functions that want to lock them
themselves anyhow (disconnects, default changes, etc).
