SDL_IOStream.3type - Man Page

#include <SDL3/SDL_iostream.h>

typedef struct SDL_IOStream SDL_IOStream;

This operates as an opaque handle. There are several APIs to create various types of I/O streams, or an app can supply an SDL_IOStreamInterface to SDL_OpenIO() to provide their own stream implementation behind this struct's abstract interface.

This struct is available since SDL 3.2.0.
