Gck.Object.get_data_full

### Method

# Gck Objectget_data_full

#### Declaration [src]

    guchar*
    gck_object_get_data_full (
      GckObject* self,
      gulong attr_type,
      GckAllocator allocator,
      GCancellable* cancellable,
      gsize* n_data,
      GError** error
    )

#### Description [src]

Get the data for the specified attribute from the object. For convenience the returned data has an extra null terminator, not included in the returned length.

This call may block for an indefinite period.

This method is not directly available to language bindings.

#### Parameters

`attr_type`

  Type: `gulong`

  The attribute to get data for.

`allocator`

  Type: `GckAllocator`

  An allocator with which to allocate memory for the data, or `NULL` for default.

`cancellable`

  Type: `GCancellable`

  Optional cancellation object, or `NULL`.

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

`n_data`

  Type: `gsize*`

  The length of the resulting data.

  The argument will be set by the function.

`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 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: An array of `guchar`

The resulting PKCS#11 attribute data, or `NULL` if an error occurred.

The length of the array is in the `n_data` argument.
The caller of the method takes ownership of the data, and is responsible for freeing it.
