SDL_FreeRW

Use this function to free an SDL_RWops structure allocated by SDL_AllocRW().

Syntax

void SDL_FreeRW(SDL_RWops* area)

Function Parameters

area

the SDL_RWops structure to be freed

Code Examples

/* this would be your SDL_RWops implementation's "close" method. */
void close_my_rwops(SDL_RWops *rw)
{
    if (rw != NULL) {
        /* close any other resources. */
        SDL_FreeRW(rw);
    }
}

Remarks

Applications do not need to use this function unless they are providing their own SDL_RWops implementation. If you just need a SDL_RWops to read/write a common data source, you should use the built-in implementations in SDL, like SDL_RWFromFile() or SDL_RWFromMem(), etc, and call the close method on those SDL_RWops pointers when you are done with them.

Only use SDL_FreeRW() on pointers returned by SDL_AllocRW(). The pointer is invalid as soon as this function returns. Any extra memory allocated during creation of the SDL_RWops is not freed by SDL_FreeRW(); the programmer must be responsible for managing that memory in their close method.
