St.TextureCache.load

### Method

# St TextureCacheload

#### Declaration [src]

    CoglTexture*
    st_texture_cache_load (
      StTextureCache* cache,
      const char* key,
      StTextureCachePolicy policy,
      StTextureCacheLoader load,
      void* data,
      GError** error
    )

#### Description [src]

Load an arbitrary texture, caching it. The string chosen for `key` should be of the form “type-prefix:type-uuid”. For example, “url:file:///usr/share/icons/hicolor/48x48/apps/firefox.png”, or “stock-icon:gtk-ok”.

This method is not directly available to language bindings.

#### Parameters

`key`

  Type: `const char*`

  Arbitrary string used to refer to item.

  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

`policy`

  Type: `StTextureCachePolicy`

  Caching policy.

`load`

  Type: `StTextureCacheLoader`

  Function to create the texture, if not already cached.

`data`

  Type: `void*`

  User data passed to `load`.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `CoglTexture`

A newly-referenced handle to the texture.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
