NAME¶

SDL_OpenIO - Create a custom SDL_IOStream .

HEADER FILE¶

Defined in SDL3/SDL_iostream.h

SYNOPSIS¶

#include "SDL3/SDL.h"

SDL_IOStream* SDL_OpenIO(const SDL_IOStreamInterface *iface, void *userdata);

DESCRIPTION¶

Applications do not need to use this function unless they are providing their own SDL_IOStream
implementation. If you just need an

SDL_IOStream
to read/write a common data source, you should use the built-in implementations in SDL, like

SDL_IOFromFile () or SDL_IOFromMem (), etc.

You must free the returned pointer with SDL_CloseIO ().

This function makes a copy of iface and the caller does not need to keep this data around after this call.

FUNCTION PARAMETERS¶

iface

The function pointers that implement this SDL_IOStream .

userdata

The app-controlled pointer that is passed to iface's functions when called.

RETURN VALUE¶

Returns a pointer to the allocated memory on success, or NULL on failure; call SDL_GetError () for more information.

AVAILABILITY¶

This function is available since SDL 3.0.0.
