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 method.

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 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: 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 returned data, and is responsible for freeing it.
