You can add your code example here

This structure should be treated as read-only, except for pixels, which, if not NULL, contains the raw pixel data for the surface.

The currently supported flags for SDL_Surface are:
or
flags may be 0 or any of the following:

SDL_PREALLOC	surface uses preallocated memory
SDL_RLEACCEL	surface is RLE encoded

Evaluates to true if the surface needs to be locked before access.

#define SDL_MUSTLOCK(S) (((S)->flags & SDL_RLEACCEL) != 0)
