SDL_realloc - Change the size of allocated memory.

       This function is available since SDL 3.2.0.

       The memory returned by this function must be freed with

       SDL_free ().

       If size is 0, it will be set to 1. Note that this is unlike some other C runtime realloc implementations,
       which may treat realloc(mem,0) the same way as free(mem) .

       If mem is NULL, the behavior of this function is equivalent to

       SDL_malloc (). Otherwise, the function can have one of three possible outcomes:

       • If it returns the same pointer as mem , it means that mem was resized
         in place without freeing.

       • If it returns a different non-NULL pointer, it means that mem was freed
         and cannot be dereferenced anymore.

       • If it returns NULL (indicating failure), then mem will remain valid and
         must still be freed with SDL_free ().

       If the allocation is successfully resized, the returned pointer is guaranteed to be aligned to either the
       fundamentalalignment ( alignof(max_align_t) in C11 and later) or 2sizeof(void ) , whichever is smaller.

mem    a pointer to allocated memory to reallocate, or NULL.

       size   the new size of the memory.
