the pointer to the actual pixel data; see Remarks for details (read-write) |
void* |
userdata |
an arbitrary pointer you can set (read-write) |
int |
locked |
used for surfaces that require locking (internal use) |
void* |
lock_data |

Remarks
With most surfaces you can access the pixels directly. Surfaces that have been optimized with SDL_SetSurfaceRLE() should be locked with SDL_LockSurface() before accessing pixels. When you are done you should call SDL_UnlockSurface() before blitting.
