# SDL\_OpenStorage(3)

Opens up a container using a client-provided storage interface.

## NAME

SDL\_OpenStorage - Opens up a container using a client-provided storage interface.

## HEADER FILE

Defined in SDL3/SDL\_storage.h

## SYNOPSIS

```

**SDL\_Storage \* SDL\_OpenStorage(const SDL\_StorageInterface \*iface, void \*userdata);**

## DESCRIPTION

Applications do not need to use this function unless they are providing their own  **SDL\_Storage**\
  implementation. If you just need an

**SDL\_Storage** , you should use the built-in implementations in SDL, like  **SDL\_OpenTitleStorage** () or

**SDL\_OpenUserStorage** ().

This function makes a copy of **iface** and the caller does not need to keep it around after this call.

## FUNCTION PARAMETERS

- *iface*

  the interface that implements this storage, initialized using  **SDL\_INIT\_INTERFACE** ().

- *userdata*

  the pointer that will be passed to the interface functions.

## RETURN VALUE

( **SDL\_Storage**\
  \*) Returns a storage container on success or NULL on failure; call  **SDL\_GetError** () for more information.

## AVAILABILITY

This function is available since SDL 3.2.0.
