SDL_OpenIO3
Create a custom sdl_iostream .
Usage
#include "SDL3/SDL.h"
SDL_IOStream * SDL_OpenIO(const SDL_IOStreamInterface *iface, void *userdata);
Header file
Defined in SDL3/SDL_iostream.h
Overview
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.
Function parameters
- iface
-
the interface that implements this
SDL_IOStream, initialized usingSDL_INIT_INTERFACE().
- 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.
Thread safety
It is safe to call this function from any thread.
