SDL_OpenIO

Header File

Syntax

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

Function Parameters

const SDL_IOStreamInterface *	iface	the interface that implements this SDL_IOStream, initialized using SDL_INIT_INTERFACE().
void *	userdata	the pointer that will be passed to the interface functions.

Return Value

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

Remarks

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.

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

Version

This function is available since SDL 3.1.3.
