SDL_LockAudioStream - Lock an audio stream for serialized access.
Contents
Availability
This function is available since SDL 3.2.0.
Description
Each SDL_AudioStream
has an internal mutex it uses to protect its data structures from threading conflicts. This function
allows an app to lock that mutex, which could be useful if registering callbacks on this stream.
One does not need to lock a stream to use in it most cases, as the stream manages this lock internally.
However, this lock is held during callbacks, which may run from arbitrary threads at any time, so if an
app needs to protect shared data during those callbacks, locking the stream guarantees that the callback
is not running while the lock is held.
As this is just a wrapper over SDL_LockMutex
for an internal lock; it has all the same attributes (recursive locks are allowed, etc).
Function Parameters
stream the audio stream to lock.
