Function SDL_LoadFileAsync 

pub unsafe extern "C" fn SDL_LoadFileAsync(
    file: *const c_char,
    queue: *mut SDL_AsyncIOQueue,
    userdata: *mut c_void,
) -> bool

Load all the data from a file path, asynchronously.

This function returns as quickly as possible; it does not wait for the read to complete. On a successful return, this work will continue in the background. If the work begins, even failure is asynchronous: a failing return value from this function only means the work couldn’t start at all.

The data is allocated with a zero byte at the end (null terminated) for convenience. This extra byte is not included in SDL_AsyncIOOutcome’s bytes_transferred value.

This function will allocate the buffer to contain the file. It must be deallocated by calling SDL_free() on SDL_AsyncIOOutcome’s buffer field after completion.

An SDL_AsyncIOQueue must be specified. The newly-created task will be added to it when it completes its work.

Parameter: file the path to read all available data from. Parameter: queue a queue to add the new SDL_AsyncIO to. Parameter: userdata an app-defined pointer that will be provided with the task results. Returns: true on success or false on failure; call SDL_GetError() for more information.

Thread Safety: It is safe to call this function from any thread.

Available Since: This function is available since SDL 3.2.0.
