SDL_IOFromDynamicMem3
Use this function to create an sdl_iostream that is backed by dynamically allocated memory.
Usage
#include "SDL3/SDL.h"
SDL_IOStream * SDL_IOFromDynamicMem(void);
Header file
Defined in SDL3/SDL_iostream.h
Overview
This supports the following properties to provide access to the memory and control over allocations:
• SDL_PROP_IOSTREAM_DYNAMIC_MEMORY_POINTER :
a pointer to the internal memory of the stream. This can be set to NULL
to transfer ownership of the memory to the application, which should free
the memory with SDL_free (). If this is done, the next
operation on the stream must be SDL_CloseIO ().
• SDL_PROP_IOSTREAM_DYNAMIC_CHUNKSIZE_NUMBER :
memory will be allocated in multiples of this size, defaulting to 1024.
Return value
( SDL_IOStream
*) Returns a pointer to a new
SDL_IOStream
structure or NULL on failure; call
SDL_GetError () for more information.
Thread safety
It is safe to call this function from any thread.
