# SDL_DestroyRW

Use this function to free an [SDL_RWops](SDL_RWops) structure allocated by [SDL_CreateRW](SDL_CreateRW)().

## Syntax

```c
void SDL_DestroyRW(SDL_RWops *context);

```

## Function Parameters

|                 |                                                  |
| --------------- | ------------------------------------------------ |
| **context**     | the [SDL_RWops](SDL_RWops) structure to be freed |

## Remarks

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

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

## Version

This function is available since SDL 3.0.0.
