NAME

       SDL_IOFromDynamicMem - Use this function to create an SDL_IOStream
        that is backed by dynamically allocated memory.

HEADER FILE

       Defined in SDL3/SDL_iostream.h

SYNOPSIS

       #include "SDL3/SDL.h"

       SDL_IOStream * SDL_IOFromDynamicMem(void);

DESCRIPTION

       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.

AVAILABILITY

       This function is available since SDL 3.2.0.
