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 RWops implementation's "close" method. */
void close_my_rwops(SDL_RWops *rw)
{
if(rw != NULL) {
/* close any other resources. */
SDL_FreeRW(rw);
}
}
Remarks
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 RWops is not freed by SDL_FreeRW(); the programmer must be responsible for managing that memory in their close method.
