GLib.Variant.get_string

### Method

# GLib Variantget_string

since: 2.24

#### Declaration [src]

    const gchar*
    g_variant_get_string (
      GVariant* value,
      gsize* length
    )

#### Description [src]

Returns the string value of a `GVariant` instance with a string type. This includes the types `G_VARIANT_TYPE_STRING`, `G_VARIANT_TYPE_OBJECT_PATH` and `G_VARIANT_TYPE_SIGNATURE`.

The string will always be UTF-8 encoded, will never be `NULL`, and will never contain nul bytes.

If `length` is non-`NULL` then the length of the string (in bytes) is returned there. For trusted values, this information is already known. Untrusted values will be validated and, if valid, a `strlen()` will be performed. If invalid, a default value will be returned — for `G_VARIANT_TYPE_OBJECT_PATH`, this is `"/"`, and for other types it is the empty string.

It is an error to call this function with a `value` of any type other than those three.

The return value remains valid as long as `value` exists.

Available since: 2.24

#### Parameters

`length`

  Type: `gsize*`

  A pointer to a #gsize, to store the length.

  The argument will be set by the function.
  The argument can be `NULL`.

#### Return value

Type: `const gchar*`

The constant string, UTF-8 encoded.

The returned data is owned by the instance.
The value is a NUL terminated UTF-8 string.
