### Function

# Json gvariant_deserialize_data

since: 0.14

#### Declaration [src]

    GVariant*
    json_gvariant_deserialize_data (
      const gchar* json,
      gssize length,
      const gchar* signature,
      GError** error
    )

#### Description [src]

Converts a JSON string to a `GVariant` value.

This function works exactly like `json_gvariant_deserialize()`, but takes a JSON encoded string instead.

The string is first converted to a `JsonNode` using `JsonParser`, and then `json_gvariant_deserialize` is called on the node.

The returned variant has a floating reference that will need to be sunk by the caller code.

Available since: 0.14

#### Parameters

`json`

  Type: `const gchar*`

  A JSON data string.

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

`length`

  Type: `gssize`

  The length of `json`, or -1 if `NUL`-terminated.

`signature`

  Type: `const gchar*`

  A valid `GVariant` type string.

  The argument can be `NULL`.
  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`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 left initialized to `NULL` by the function 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: `GVariant`

A newly created `GVariant`D compliant.

The data is owned by the called function.
The return value can be `NULL`.
