NAME
SDL_LoadFileAsync - Load all the data from a file path, asynchronously.
HEADER FILE
Defined in SDL3/SDL_asyncio.h
SYNOPSIS
#include "SDL3/SDL.h" bool SDL_LoadFileAsync(const char *file, SDL_AsyncIOQueue *queue, void *userdata);
DESCRIPTION
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 This function will allocate the buffer to contain the file. It must be deallocated by calling SDL_free () on SDL_AsyncIOOutcome An SDL_AsyncIOQueue must be specified. The newly-created task will be added to it when it completes its work.
FUNCTION PARAMETERS
file the path to read all available data from. queue a queue to add the new SDL_AsyncIO to. userdata an app-defined pointer that will be provided with the task results.
RETURN VALUE
Returns true on success or false on failure; call SDL_GetError () for more information.
AVAILABILITY
This function is available since SDL 3.2.0.
