Syntax

SDL_RWops* SDL_RWFromMem(void* mem,
                         int   size)

mem	^{a pointer to the memory location}
size	^{the size of the memory location} ???

A pointer to the SDL_RWops structure that is created, or NULL on failure.

char bitmap[310000];
SDL_RWops *rw;

rw = SDL_RWFromMem(bitmap, sizeof(bitmap));
SDL_SaveBMP_RW(screen, rw, 0);

If the memory is not writable, use SDL_RWFromConstMem() instead.
