SDL_LoadFileAsync

Load all the data from a file path, asynchronously.

Header File

Syntax

bool SDL_LoadFileAsync(const char *file, SDL_AsyncIOQueue *queue, void *userdata);

Function Parameters

const char *	file	the path to read all available data from.
SDL_AsyncIOQueue *	queue	a queue to add the new SDL_AsyncIO to.
void *	userdata	an app-defined pointer that will be provided with the task results.

Return Value

(bool) Returns true on success or false on failure; call SDL_GetError() for more information.

Remarks

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.

Version

This function is available since SDL 3.2.0.
